Not in warfare alone: Conical timber lodges in the Central Rocky Mountains and Northwestern Plains by Carl M. Davis Published online: 21 May 2014 Abstract Conical timber lodges are a well known but little investigated archaeological feature of the Central Rocky Mountains and Northwestern Plains. These perishable wood structures are commonly regarded as war lodges or short-term shelters built by Plains Indian groups during the Protohistoric and Historic periods. Archaeological, ethnohistorical, and ethnographic data show that this interpretation is too narrow. Conical timber lodges served a diversity of purposes as temporary shelters, special activity sites, and domiciles. Conical timber lodges are widely distributed across the Northwestern Plains, Central Rocky Mountains, and Wyoming basin (Figure 1). Archaeological investigation of these fragile wood features has been sporadic, unsystematic, and intuitive. Most are presumed to be war lodges or short-term shelters built by native peoples during the Protohistoric and Historic periods, dating from approximately A.D. 1700 to A.D. 1900 (Frison 1991:123; Kornfeld et al. 2010:129–138). Kornfeld, Marcel, George C. Frison, and Mary Lou Larson (2010) Prehistoric Hunter-Gatherers of the High Plains and Rockies. Left Coast Press, Walnut Creek. Although standing structures of any type from the Protohistoric and Historic periods are rare in the Central Rocky Mountains and Northwestern Plains, an up-to-date inventory of conical timber lodge features does not exist. Figure 1. Known distribution of conical timber lodges in eastern Idaho, Montana, North Dakota, South Dakota, and Wyoming. In this paper, I provide an overview of conical timber lodges in east-central Idaho, Montana, western North and South Dakota, and Wyoming. My goals are to: (1) clarify perishable wood feature nomenclature; (2) review the known distribution of conical timber lodges; (3) offer tentative interpretations of age, construction, use, and cultural association; and (4) encourage more systematic conical lodge investigations before this perishable feature type entirely disappears. Wood lodge nomenclature The conical timber lodge is one type of perishable structure within a larger group of wood and brush features found throughout the Central Rocky Mountains and Northwestern Plains, including but not limited to corrals, catch-pens, breastworks, fortifications, cribbed log structures, and hunting blinds. The aboriginal use of certain types of wood structures is relatively well understood, such as timber drive lanes and catch-pens used to hunt antelope, deer, and mountain sheep (Eakin 2005 Eakin, Daniel H. (2005) Evidence for Shoshonean Bighorn sheep Trapping and Early Historic Occupation in the Absaroka Mountains of Northwest Wyoming.

(1974) The LaMarche Game Trap: An Early Historic Game Trap in Southwestern Montana. Plains Anthropologist 20:207–215. The function of other perishable feature types, including conical timber lodges, remains problematic. The terms conical timber lodge and wickiup have been used interchangeably in the archaeological literature of the Rocky Mountains and Northwestern Plains for decades (e.g., Conner 1966a; Davis 1975 Davis, Carl M. (1975) Wickiup Cave. Plains Anthropologist 20:297–305.[Taylor & Francis Online], Hoffman 1961 Hoffman, J. Jacob (1961) A Preliminary Archaeological Survey of Yellowstone National Park.

Scott 1988 Scott, Douglas D. (1988) Conical Timber Lodges in Colorado or Wickiups in the Woods. In Archaeology of the Eastern Ute: A Symposium, edited by Paul R. Nickens, pp. 45–53. Colorado Council of Professional Archaeologists Occasional Papers No. 1. Colorado Council of Professional Archaeologists, Denver, Colorado. White and White 2012 White, David R. M., and Katharine L. White (2012) Wickiups of the Greater Yellowstone Ecosystem: Conical Timber Lodges within Bridger-Teton National Forest, Grand Teton National Forest, Shoshone National Forest, and Yellowstone National Park. National Park Service, Yellowstone Center for Resources, Yellowstone National Park, Wyoming. This precedent was set by early western travellers and anthropologists who frequently used the term wickiup (among others) to describe the wide range of pole and brush shelters they observed (e.g., Grinnell 1927). This terminology was later applied uncritically by archaeologists to wood structures found in the Central Rockies and Northwestern Plains. Nonetheless, the term conical timber lodge is used exclusively in this paper to describe conical-shaped, vertical pole structures that are free-standing or braced against a tree or rock face. Braced conical structures have also been called ‘leaning pole lodges’ (Frison 1991:127, Figure 2.77), implying that they may be a separate perishable structure type. However, because of their conical, vertical pole configuration, they are included as conical lodges for purposes of this overview. Figure 2. Conical lodge plan views showing proximity of poles, bark, and rocks: Big Sheep Creek Wickiup Cave, 24BE601, lower; Cottonwood Creek, 24MA602, upper. See also Davis and Scott (1987 Davis, Carl M., and Sara A. Scott (1987) The Pass Creek Wickiups: Northern Shoshone Hunting Lodges in Southwest Montana. Plains Anthropologist 32:83–92.[Taylor & Francis Online], : Figure 4, page 86. Whether free-standing or braced, conical lodges are either open with a few widely spaced, vertical poles or tightly enclosed with numerous vertical poles, branches, boughs, and bark slabs (Figure 2). The number of wood poles comprising a conical lodge varies, as does the configuration of interlocking poles at the apex. Live and dead Douglas fir (Pseudotsuga menziesii), lodgepole pine (Pinus contorta), limber pine (Pinus flexilis), whitebark pine (Pinus albicaulis), spruce (Picea spp.), aspen (Populus tremuloides), cottonwood (Populus ssp.), ash (Franxinu ssp.), juniper (Juniperus communis), and other tree species were used in lodge construction. Occasionally, stones and earth were stacked around their base. Lodges frequently contain interior fire hearths and artifacts. In contrast, the term wickiup is reserved for the variously configured, frequently dome-shaped structures typically found in the Great Basin and American Southwest. This diverse perishable structure type was made of poles, branches, brush, rushes and grass thatching, mats, basketry, hide, boards, cloth, or canvass (e.g., Irving 1961:221–222; Huscher and Huscher 1943 Huscher, Betty H., and Harold A. Huscher (1943) The Hogan Builders of Colorado. Southwestern Lore 9(11):1–92. [Google Scholar]; Murphy and Murphy 1986:294, Figure 5). Archaeologically documented wickiups are attributed to Apache, Bannock, Navaho, Paiute, Shoshone, Ute, and other native groups (Arkush 1987 Arkush, Brooke S. (1987) Historic Northern Paiute Winter Houses in the Mono Basin, California. Journal of California and Great Basin Anthropology 9:174–187; Martin et al. 2005 Martin, Curtis, Richard Ott, and Nicole Darnell (2005) The Colorado Wickiup Project Volume I: Context, Data Assessment, and Strategic Planning. Prepared by Dominquez Archaeological Research Group, Inc. Submitted to the Colorado Historical Society, Denver. ; Seymour 2009 Seymour, Deni J. (2009) Nineteenth-century Apache Wickiups: Historically Documented Models for Archaeological Signatures of the Dwellings of Mobile People. Antiquity 83:157– 164.[Crossref], [Web of Science ®], ). Given their simplicity of construction and state of preservation, the typological distinction between a wickiup and conical lodge is occasionally problematic, especially at the margins of the Northwestern Plains (see Scott 1988 Scott, Douglas D. (1988) Conical Timber Lodges in Colorado or Wickiups in the Woods. In Archaeology of the Eastern Ute: A Symposium, edited by Paul R. Nickens, pp. 45–53. Colorado Council of Professional Archaeologists Occasional Papers No. 1. Colorado Council of Professional Archaeologists, Denver, Colorado. ). A precise nomenclature awaits more comprehensive recording, investigation, and interregional comparisons. Conical timber lodges differ from cribbed log structures on the Northwestern Plains. These rectangularshaped and pentagonal-shaped wood features were built of horizontally laid timbers which cribbed inward at each tier, apparently to support a timber, hide, or brush roof (Lowie 1922:259; Mulloy 1965 Mulloy, William (1965) The Indian Village at Thirty Mile Mesa, Montana. University of Wyoming Publications, Laramie, Wyoming 31(1). :3; Voget 1977 Voget, Fred W. (1977) Timber Shelters of the Crow Indians. Archaeology in Montana 18(2–3):1–18. :3). Like many conical lodges, the walls of cribbed log structures were covered with sticks, brush, boughs, and rocks (Frison 1991:96, Figure 2.54). Used by native peoples from the Late Prehistoric through the Historic periods, some cribbed log structures probably served as seasonal residences while others functioned as temporary shelters, defensive breastworks, or fortresses (Adams 2010 Adams, Richard (2010) Archaeology with Altitude: Late Prehistoric Settlement and Subsistence in the Northern Wind River Range, Wyoming. Ph.D. dissertation, Department of Anthropology, University of Wyoming, Laramie. ; Davis et al. 1994 Davis, Carl M., James D. Keyser, and Cynthia D. Craven (1994) Coyote House: Prehistoric Butte Top Occupation in the Pine Parklands. Archaeology in Montana 35(2):5–57. :49–55; Frison 1991:123; Johnson et al. 1998:111–112; Loendorf 1969 Loendorf, Lawrence L. (1969) Pryor Mountain Archaeology. Archaeology in Montana 10(2):21– 52. :44; Moe 1974 Moe, Richard B. (1974) Two Cribbed Log Structure Sites. Archaeology in Montana 15(2):27–34. ). Although cribbed log structures are likely part of a wood shelter continuum in this region that includes conical lodges, the chronological, functional, and cultural relationships between these two perishable structure types are presently not well understood. Research context Conical timber lodge research has been sporadic across the Central Rocky Mountains and Northwestern Plains due to the scarcity of these features, coupled with the traditional research focus on stratified occupations, bison kills, and other potentially more informative archaeological site types. As a consequence, conical timber lodges have received relatively little attention in archaeological syntheses for this region (e.g., Frison 1991:126, Figure 2.75; Kornfeld et al. 2010 Kornfeld, Marcel, George C. Frison, and Mary Lou Larson (2010) Prehistoric Hunter-Gatherers of the High Plains and Rockies. Left Coast Press, Walnut Creek. ; MacDonald 2012 MacDonald, Douglas H. (2012) Montana before History 11,000 Years of Hunter-Gatherers in the Rockies and Plains. Mountain Press Publishing Company, Missoula, Montana. :150). Kidwell (1969 Kidwell, Arthur Spaulding (1969) The Conical Timbered Lodge on the Northwestern Plains: Historical, Ethnological, and Archaeological Evidence. Archaeology in Montana 10(4):1–49. ) completed the first inventory of conical timber lodges on the Northwestern Plains. He relied on early publications and field notes by Conner (1963 Conner, Stuart W. (1963) Evans Site. Trowel and Screen 4(8):2. , 1966a, 1966b), Des Rosier (1965 Des Rosier, Fred L. (1965) Kutenai War Lodges. Archaeology in Montana 6(1):14. ), Malouf (1963 Malouf, Carling (1963) Battle Pits and War Lodges. Archaeology in Montana 2(5):1–11. Missoula. ), Mulloy (1965 Mulloy, William (1965) The Indian Village at Thirty Mile Mesa, Montana. University of Wyoming Publications, Laramie, Wyoming 31(1). ), and others. Based largely on ethnohistorical accounts, Kidwell concluded that conical lodges functioned primarily as temporary shelters for travelling war parties of Plains Indians such as the Blackfeet. Kidwell's war lodge hypothesis relied on Ewers (1944 Ewers, John C. (1944) The Blackfoot War Lodge: Its Construction and Use. American Anthropologist 46:182–192.[Crossref], ) and others but, as this paper illustrates, his interpretation is too narrow to fit all conical lodge features. Conical timber lodges in North and South Dakota were first described by Will (1909 Will, George F. (1909) Some Observations Made in Northwestern South Dakota. American Anthropologist 11:257– 265.[Crossref], ), Wilson (1928 Wilson, Gilbert L. (1928) Hidatsa Eagle Trapping. Anthropological Papers 30, Pt. 4. American Museum of Natural History, New York. ), Bowers (1950 Bowers, Alfred (1950) Mandan Social and Ceremonial Organization. University of Chicago Press, Illinois. ), and Howard (1954 Howard, J. H. (1954) Yanktonai Dakota Eagle Trapping. Southwestern Journal of Anthropology 10:60–74.[Crossref], ), and later by Metcalf (1963 Metcalf, George (1963) Small Sites on and about Forth Berthold Indian Reservation, Garrison Reservoir, North Dakota. Bureau of American Ethnology Bulletin 185, River Basin Survey Papers No. 26, Smithsonian Institution, Washington, DC. ), Allen (1983 Allen, Walter E. (1983) Eagle Trapping in the Little Missouri Badlands. North Dakota History Journal of the Northern Plains 50:4–22. ), and Kuehn (1989). These ethnographers and archaeologists concluded that conical structures in the Dakotas were predominantly ceremonial lodges associated with eagle trapping among the Arikara, Hidatsa, Mandan, Yanktonai Dakota, and other middle Missouri River tribal groups during the Protohistoric and Historic periods. Kingsbury's (1986) inventory of conical lodges in southwest Montana proposed that wood pole structures in this mountainous region were built by the Northern (Lemhi) Shoshone. Kingsbury noted the rapidly deteriorating condition of the conical lodges at the sites he visited, as well as the deleterious effects of public visitation at the single conical lodge in Big Sheep Creek Cave (24BE601) (Figure 3). His management recommendations included placement of rebar markers, recognizing that many conical lodges would soon disappear through natural and human agencies. Figure 3. Big Sheep Creek Wickiup Cave conical lodge, 24BE601, southwest Montana. Wenker (1992 Wenker, Chris T. (1992) Native American Timber Structures of the Northwestern Plains. Archaeology in Montana 33(1):25–33. ) completed a comparative analysis of conical, cribbed log, and other timber structure types on the Northwestern Plains. He distinguished between primary (conical and cribbed log) and secondary (lean-to and truncated) structural features and focused on the tripedal and quadrupedal pole foundations of conical lodges as a possible indicator of cultural association. His findings regarding pole foundations and cultural association were inconclusive beyond the Little Missouri River region of North and South Dakota, where four pole foundations appeared to prevail archaeologically. Conical lodges in the Yellowstone National Park (YNP) have long elicited public and professional interest, due in part to Park Superintendent Philetus Norris's (1880) frequent mention of the many pole and brush lodges in the park area and their assumed use by Bannock, Crow, and Shoshone bands. Archaeological surveys in the 1950s and 1960s, both within and adjacent to the park, led to the recording and investigation of several lodges, particularly at the well-known Lava Creek site (48YE2) (Hoffman 1961 Hoffman, J. Jacob (1961) A Preliminary Archaeological Survey of Yellowstone National Park. Unpublished Master's thesis, Department of Anthropology, University of Montana, Missoula. ; Napton 1966 Napton, Lewis K. (1966) Canyon and Valley: Preliminary Archaeological Survey of the Gallatin Area, Montana. Unpublished Master's thesis, Department of Anthropology, University of Montana, Missoula. ; Replogle 1956 Replogle, Wayne (1956) Yellowstone's Bannock Indian Trails. Yellowstone Library and Museum Association, Yellowstone National Park. ; Shippee 1971 Shippee, J. Mett (1971) Wickiups of Yellowstone Park. Plains Anthropologist 16:74–75. ; Taylor et al. 1964). It is likely that many structures noted by Norris and early park visitors are now deteriorated beyond recognition or were consumed by fire, such as the 1988 wildfire which burned 36 percent of the YNP (National Park Service 2008 National Park Service (2008) The Yellowstone Fires of 1988. U.S. Department of Interior, National Park Service, Yellowstone National Park. http://www.nps.gov/yell/planyourvisit/upload/firesupplement.pdf, accessed June 2011. ). Recently, the National Park Service (NPS) funded a conical lodge study within the Grand Teton and Yellowstone National Parks and the Bridger-Teton and Shoshone National Forests in northwest Wyoming (White and White 2012 White, David R. M., and Katharine L. White (2012) Wickiups of the Greater Yellowstone Ecosystem: Conical Timber Lodges within Bridger-Teton National Forest, Grand Teton National Forest, Shoshone National Forest, and Yellowstone National Park. National Park Service, Yellowstone Center for Resources, Yellowstone National Park, Wyoming. ). The NPS study was an ethnographic overview and inventory of known conical lodges in northwest Wyoming and, less comprehensively, in Montana and the Dakotas. As a part of this study, representatives from 11 tribes offered their own interpretations of conical lodge function, including that pole lodges were primarily used as temporary shelters among a variety of native groups who once occupied or used the park area and its surrounds (White and White 2012 White, David R. M., and Katharine L. White (2012) Wickiups of the Greater Yellowstone Ecosystem: Conical Timber Lodges within Bridger-Teton National Forest, Grand Teton National Forest, Shoshone National Forest, and Yellowstone National Park. National Park Service, Yellowstone Center for Resources, Yellowstone National Park, Wyoming. :59–62). My overview was precipitated by a U.S. Forest Service Northern Region concern regarding the vulnerability of existing conical timber lodges and other wood structures to wildfire. Conical lodge data presented herein were derived from State Historic Preservation Office (SHPO) databases, cultural site records, cultural resource management (CRM) reports, publications, and correspondence with local informants and state, federal, and university archaeologists. SHPO databases variously identified conical timber lodges as prehistoric wood structures, pole lodges, war lodges, wickiups, pole lean-tos, timber lodges, brush and wood shelters, and wood habitation sites. However, in this paper I review only those that correspond to the definition provided above. In addition to this diverse nomenclature, conical timber lodge reporting is highly uneven. Basic description such as lodge location, environmental setting, interior size, and wood pole genera/species is frequently vague or entirely missing in many cultural site records and reports. Because of this situation, my overview necessarily excludes poorly documented or nebulous conical lodge references, wood features that do not seem to qualify as conical lodges, and ambiguous structures that are likely to be of modern origin (White and White 2012 White, David R. M., and Katharine L. White (2012) Wickiups of the Greater Yellowstone Ecosystem: Conical Timber Lodges within Bridger-Teton National Forest, Grand Teton National Forest, Shoshone National Forest, and Yellowstone National Park. National Park Service, Yellowstone Center for Resources, Yellowstone National Park, Wyoming. : Table 4.1). Some questionable sites may legitimately qualify as aboriginal conical timber lodges upon further field examination and research. Others may not. Over the past several decades, I visited conical lodges in southwest Montana but pole lodge structures in the other states are described using existing site information. A total of 92 conical lodges at 64 archaeological sites are the basis of this overview. Table 1 of 2 (actual table not available) –, no data; all measurements are in meters (m) at maximum dimension. Wood Type: AS, aspen; CW, cottonwood; C, cedar; LP, Lodgepole pine; DF, Douglas fir; JP, juniper; SP, spruce; and WbP, Whitebark Pine.

Conical timber lodges in Idaho, Montana, North and South Dakota Conical lodge distribution Conical timber lodges are scattered throughout the Central Rocky Mountain and Northwestern Plains region (Figure 1). Several patterns are apparent in the extant lodge distribution data. Over half of the known conical lodges are concentrated in the mountain ranges of east-central Idaho, southwest Montana, and northwest Wyoming. One cluster of lodges in southwest Montana occupies an area that includes parts of the Beaverhead, Blacktail, Centennial, Ruby, and Tendoy mountains (Table 1). Of these, Big Sheep Creek Wickiup Cave (24BE601) is unique because of its location inside a limestone rockshelter (Davis 1975 Davis, Carl M. (1975) Wickiup Cave. Plains Anthropologist 20:297–305.[Taylor & Francis Online], ) (Figures 2 and 3). With the exception of Wickiup Cave, no southwest Montana lodges have been thoroughly investigated. Artifacts and an interior hearth were observed at the Garden Creek No. 2 lodge (24MA601) in the Ruby Range but none were found at the nearby Garden Creek No. 1 (24MA81) and Cottonwood lodges (24MA602), the latter of which is shown in MacDonald (2012 MacDonald, Douglas H. (2012) Montana before History 11,000 Years of Hunter-Gatherers in the Rockies and Plains. Mountain Press Publishing Company, Missoula, Montana. :150) but is mislocated in the Pryor Mountains. The Trail Spring lodge (24JF1019) in the Deer Lodge Range still stands and may be associated with nearby stone hunting blinds and other archaeological remains, which were attributed to the Mountain (Tukudika, Sheep Eater) Shoshone (Pallister 1992 Pallister, Philip D. (1992) The Bull Mountain Wickiup and Dry-Laid Masonry Structures: A Tukudika Complex? Archaeology in Montana 33(2):33–59. ). Artifacts were not in evidence at the Pass Creek site when it was recorded and mapped but no subsurface testing occurred there (Davis and Scott 1987 Davis, Carl M., and Sara A. Scott (1987) The Pass Creek Wickiups: Northern Shoshone Hunting Lodges in Southwest Montana. Plains Anthropologist 32:83–92.[Taylor & Francis Online], ). Two conical lodges (10CR1161, 10LH1222) are located in the Boulder and Beaverhead Mountains of east-central Idaho (Figure 4; Table 1). Both lodges are tightly enclosed with numerous vertical poles. Neither has been excavated. The dearth of reported conical lodges in the mountains of east-central Idaho and on the west slope of the Bitterroot Range is intriguing given the extensive occupation and use of the area by Northern Shoshone, Nez Perce, and other Indian tribes in the nineteenth century (Steward 1938 Steward, Julian H. (1938) Basin-Plateau Aboriginal Sociopolitical Groups. Bureau of American Ethnology Bulletin No. 120. Smithsonian Institution, Washington, DC. :186–188; Walker 1982 Walker, Deward E. Jr. (1982) Indians of Idaho. University of Idaho Press, Moscow. :28–40). A number of Indian lodges were reported here by soldiers during the short-lived Sheep Eater Campaign of 1879 (Carrey et al. 1968 Carrey, John, Col. W. C. Brown, George M. Shearer, and Aaron F. Parker (1968) The Sheep Eater Campaign (Chamberlin Basin Country): Original Accounts of the Sheepeater Indian Campaign and White People Who Later Occupied the Desolate Area. Campaign, Idaho Free Country Press, Grangeville, Idaho. ), but archaeologists have yet to locate any lodges or camps recorded in their military journals (Roberts 1983). Poor preservation and lack of archaeological survey in the rugged mountains of central Idaho may partly account for this discrepancy. Two other conical lodges in southwest Montana are located further east in the Gallatin Range near YNP, including the Wickiup Creek (24YE301) and Snowflake Pole (24GA325) sites (Conner 1966b; Napton 1966 Napton, Lewis K. (1966) Canyon and Valley: Preliminary Archaeological Survey of the Gallatin Area, Montana. Unpublished Master's thesis, Department of Anthropology, University of Montana, Missoula. ; Taylor et al. 1964) (Table 1). At Wickiup Creek, three now collapsed lodges were built of aspen poles cut with a sharp implement, possibly a metal axe. Two of the three structures were excavated in 1958 by Napton (1966 Napton, Lewis K. (1966) Canyon and Valley: Preliminary Archaeological Survey of the Gallatin Area, Montana. Unpublished Master's thesis, Department of Anthropology, University of Montana, Missoula. ). A rimless, surface fire hearth and a semi-circle of 12 cobblestones were found inside the lodge. No radiocarbon dates are available for this hearth feature. In northwest and north-central Wyoming, conical timber lodges are concentrated in the Absaroka, Bighorn, Gros Ventre, Teton, and Wind River ranges (Table 2). Of these sites, the Lava Creek Wickiup (48YE2) is the most informative because of the level of work performed (Hoffman 1961 Hoffman, J. Jacob (1961) A Preliminary Archaeological Survey of Yellowstone National Park. Unpublished Master's thesis, Department of Anthropology, University of Montana, Missoula. ; Grinnell 1927; Napton 1966 Napton, Lewis K. (1966) Canyon and Valley: Preliminary Archaeological Survey of the Gallatin Area, Montana. Unpublished Master's thesis, Department of Anthropology, University of Montana, Missoula. ; Replogle 1956 Replogle, Wayne (1956) Yellowstone's Bannock Indian Trails. Yellowstone Library and Museum Association, Yellowstone National Park. ; Shippee 1971 Shippee, J. Mett (1971) Wickiups of Yellowstone Park. Plains Anthropologist 16:74–75. ; Taylor et al. 1964). One excavated lodge contained a central hearth, obsidian flakes, and butchered elk bone. The lodges were attributed to the Bannock and Shoshone by Hoffman (1961 Hoffman, J. Jacob (1961) A Preliminary Archaeological Survey of Yellowstone National Park. Unpublished Master's thesis, Department of Anthropology, University of Montana, Missoula. ). In the mid-1980s, tree ring studies were conducted at the Soapy Dale lodge (48HO107), which was subsequently dismantled and reconstructed at the Washakie Museum in Worland, Wyoming. Such a conservation measure was fortuitous given that a conical lodge (48BH719) located in a rockshelter in the Bighorn Mountains (similar to Big Sheep Creek Wickiup Cave in Montana) was vandalized and burned before it could be fully investigated (Larson et al. 1975 Larson, T., P. Treet, and D. McGuire (1975) Wyoming Archaeological Site Form, Site Number 48BH719, Bureau of Land Management Little Mountain Survey. On file with the Wyoming State Historic Preservation Office, Laramie. ). In any event, the Alkali Creek (48FR5901) (Figure 5), Boulder Creek-Kendall (48SU7322) (Frison 1991:125, Figure 2.75), and other conical lodge sites in northwest Wyoming have received limited research. Figure 4. Red Lake conical lodge, 10CR1161, eastern Idaho. Figure 5. Alkali Creek conical lodge, 48FR5925, northwest Wyoming. Table 2 of 2 (actual table not available) –, no data; all measurements are in meters (m) at maximum dimension. Wood type: AS, aspen; CW, cottonwood; C, cedar; LP, Lodgepole pine; DF, Douglas fir; JP, juniper; SP, spruce; and WbP, Whitebark pine. Water: Ck, creek, Pd, pond, Md, meadow-marsh; and Sp, spring, Status: B, burned; C, collapsed; PC, partly collapsed; S, standing. Foundation indicates the number of poles. Nine of the lodges in northwest Wyoming are comprised of pine or aspen poles braced against a standing or dead tree (trees randomly growing through abandoned lodges are unlikely to result in such a consistent pattern of leaning poles at various sites) (Table 2). For example, at the Crystal Creek site (48TE1440) on the Bridger-Teton National Forest, two conical lodges were built around a white-bark pine tree at an elevation of approximately 2,800 m above sea level. Other poles lay on the ground surrounding the tree suggesting that the exterior pole covering was dismantled or has entirely deteriorated. Several sites contain lithic scatters whose association with the lodges is unclear. Conical lodge information from northwest Wyoming is also derived from an archaeological site where a wood structure is no longer present. Boulder Ridge (48PA2642) is a high elevation ridge system on National Forest system lands in the Absaroka Range. This archaeologically rich area contained a collapsed conical lodge, drive lanes, cairns, and several mountain sheep traps (Finley and Finley 2004). The area burned in a 2003 wildfire. Post-fire surveys sponsored by the U.S. Forest Service and completed by the Office of the Wyoming State Archaeologist and university students revealed an abundance of Protohistoric period artifacts, most likely representing Shoshonean occupation in the vicinity of the now incinerated conical pole lodge and elsewhere (Eakin 2005 Eakin, Daniel H. (2005) Evidence for Shoshonean Bighorn sheep Trapping and Early Historic Occupation in the Absaroka Mountains of Northwest Wyoming. University of Wyoming National Park Service Research Center 29th Annual Report 2005, pp. 74–86. University of Wyoming, Laramie. ; Finley and Finley 2004; Scheiber and Finley 2010 Scheiber, Laura L., and Judson Byrd Finley (2010) Mountain Shoshone Technological Transitions Across the Great Divide. In Across the Great Divide: Culture Contact and Culture Change in North America at AD 1500, edited by L. L. Scheiber, and M. Mitchell, pp. 128–148. University of Arizona Press, Tucson. :141–147). Another cluster of 13 lodges are scattered throughout the Castle, Little Belt, Little Snowy, and Pryor mountains of central Montana (Figure 1; Table 1). They are typically situated at lower elevations in these island mountain ranges; for example, the Whetstone Ridge lodges (24ME409) in the Castle Mountains are situated at about 1,500 m above sea level (Arthur 1967). Lodges in this cluster are constructed of numerous timber poles but generally lack smaller branches and bark slabs in the gaps between poles. Excavations at the Evans (24GV405) and Janich (24ML411) sites yielded gun flints, lead balls, glass beads, a brass tack, and the barrel of a Northwest gun (Conner 1963 Conner, Stuart W. (1963) Evans Site. Trowel and Screen 4(8):2. ; Johnson et al. 1988 Johnson, Ann M., Kenneth J. Feyhl, Stuart Conner, and Michael Bryant (1988) The Cremation of two Early Historic Structures in the Bull Mountains. Archaeology in Mountain 29(2):97–115. ; Joyes 1968 Joyes, Dennis (1968) The Evans Wickiup Site (24GV405). Archaeology in Montana 9(2):1–17. ). In these settings, access to upland resources may have been less important than water, security, and defensibility, implying that their use was related to hunting and warfare, as discussed further below. A small number of conical lodges are reported from the plains and basins of south and east Wyoming (Table 2). Sites such as Joe Bozovich 2 (48SW5981) comprise relatively small, compact lodges made of juniper, aspen, or fir poles. In fact, several lodges (e.g., 48SW9441, Powder Mountain) share characteristics of both a conical lodge (vertical poles, conical shape) and a wickiup (smaller size, low apex, fewer poles), attesting to the challenge of classifying wood structure types in some areas. Keyser and Poetschat (2008 Keyser, James D., and George R. Poetschat (2008) Ute Horse Raiders on the Powder Rim: Rock Art at Powder Wash, Wyoming. Oregon Archaeological Society Publication No. 19, Oregon Archaeological Society, Portland, Oregon. ) suggested that the Powder Mountain structures functioned as war lodges and are possibly associated with nearby rock art sites showing drawings of horses and combat scenes. Whatever the case, Wyoming has a long history of aboriginal shelter construction reflecting various seasonal uses of sage-covered foothills and basins during the Protohistoric and Historic periods by Shoshone, Ute, and other native groups (Frison 1971 Frison, George C. (1971) Shoshonean Antelope Procurement in the Upper Green River Basin, Wyoming. Plains Anthropologist 15:258–284. :260–261, Figure 2). A final group of conical lodges is located along the Little Missouri River of North Dakota (Allen 1983 Allen, Walter E. (1983) Eagle Trapping in the Little Missouri Badlands. North Dakota History Journal of the Northern Plains 50:4–22. ; Kuehn 1989; Metcalf 1963 Metcalf, George (1963) Small Sites on and about Forth Berthold Indian Reservation, Garrison Reservoir, North Dakota. Bureau of American Ethnology Bulletin 185, River Basin Survey Papers No. 26, Smithsonian Institution, Washington, DC. ) (Figure 6). All lodges are located within timber and brush thickets. They are of generally similar construction. Three lodges exhibit a four-pole foundation while two others are built on a three pole foundation. Six lodges are found on benches and ridge tops in the rugged badlands (32BI128, 32BI401, 32SL283, 32MZ435, 32MZ608). Site 32SL283 is a single lodge partially ringed with sandstone slabs. Figure 6. Winter Wickiup conical lodge, 32MZ435, western North Dakota. Three conical lodges are located on terraces and the floodplain of the Little Missouri River (32MZ447, 32BI847, 32DU25). Site 24B1847 was described as a pole structure covered with dirt and bark prior to a 1947 flood. Today, however, only a 3.6 m depression remains at this site. Lodge 32DU25 was built with a four-pole foundation against which long poles, shorter branches, and overlapping bark slabs were stacked (Metcalf 1963 Metcalf, George (1963) Small Sites on and about Forth Berthold Indian Reservation, Garrison Reservoir, North Dakota. Bureau of American Ethnology Bulletin 185, River Basin Survey Papers No. 26, Smithsonian Institution, Washington, DC. ). The location of floodplain lodges such as 32DU25 suggests that other conical lodges may have been lost with the construction and flooding of the Garrison Reservoir/Lake Sakakawea. Because of their relatively good condition, Allen (1983 Allen, Walter E. (1983) Eagle Trapping in the Little Missouri Badlands. North Dakota History Journal of the Northern Plains 50:4–22. :19) suggested that floodplain lodges reflected a later period of eagle trapping. Eagle trapping ended in this area in the early 1880s (Bowers 1950 Bowers, Alfred (1950) Mandan Social and Ceremonial Organization. University of Chicago Press, Illinois. :207–208). Two conical timber lodges are located in the Slim Buttes area of northwest South Dakota (Conner and Halverson 1969 Conner, Stuart W., and Samuel D. Halverson (1969) Slim Buttes Lodge. Archaeology in Montana 10(1):1–13. ). Site 39HN201 was built with some 60 aspen poles over which grass and brush were placed. Poles were stacked in two layers. The lodge was encircled with cobbles. Intact hearths were present both inside and outside of the lodge. When the structure was first observed by a local rancher in 1886, it was estimated to be only five or six years old. A second Slim Buttes lodge, first reported by George Will (1909 Will, George F. (1909) Some Observations Made in Northwestern South Dakota. American Anthropologist 11:257–265.[Crossref], ), apparently included at least two structures which were later removed by local residents prior to 1920. He also observed the ashes of hearth fire and a painted buffalo skull. In addition to this broad geographic pattern, conical lodges in east-central Idaho, southwest Montana, and northwest Wyoming tend to be located on mountain benches, terraces, ridges, and gentle slopes between about 2,000 m and 3,100 m above sea level. In these same settings, pole lodges are usually found near mountain springs, streams, or lakes. Otherwise, my attempts to correlate site attributes were problematic because of incomplete or inconsistently reported conical lodge data (see White and White 2012 White, David R. M., and Katharine L. White (2012) Wickiups of the Greater Yellowstone Ecosystem: Conical Timber Lodges within Bridger-Teton National Forest, Grand Teton National Forest, Shoshone National Forest, and Yellowstone National Park. National Park Service, Yellowstone Center for Resources, Yellowstone National Park, Wyoming. :84). Presently, most of the surviving conical lodges are found in relatively secluded or inaccessible locations. Rarely do they contain more than a few lodge features. Of the 64 known conical lodge sites, 48 (75 percent) contain a single lodge and 10 (16 percent) contain double lodges. Only a few sites contain more structures, including four lodges at Lava Creek (48YE2) in the Gallatin Range, and six (and possibly more) lodges at Replogle (48YE485) in the Absaroka Mountains (Replogle 1956 Replogle, Wayne (1956) Yellowstone's Bannock Indian Trails. Yellowstone Library and Museum Association, Yellowstone National Park. ; White and White 2012 White, David R. M., and Katharine L. White (2012) Wickiups of the Greater Yellowstone Ecosystem: Conical Timber Lodges within Bridger-Teton National Forest, Grand Teton National Forest, Shoshone National Forest, and Yellowstone National Park. National Park Service, Yellowstone Center for Resources, Yellowstone National Park, Wyoming. :42). This pattern of single or only a few lodges, coupled with their isolation, contrasts with many Northwestern Plains tipi ring sites, which typically are in more accessible settings and contain multiple, stone circle features situated in close proximity to each other (e.g., Davis 1983 Davis, Leslie B. (1983) Stone Circles in the Montana Rockies: Relicit Households and Transitory Communities. In Microcosm to Macrocosm: Advances in Tipi Ring Investigation and Interpretation, edited by Leslie B. Davis, pp. 235–278. Plains Anthropologist Memoir 19. ). This divergence may reflect, in part, the differing environmental and cultural contexts in which conical timber lodges and pole and hide tipis were built and used. Lastly, the small number of known conical lodges pales in comparison to the numerous ethnohistorical and ethnographic accounts of their widespread use across the Northwestern Plains during the Protohistoric and Historic periods (e.g., Kidwell 1969 Kidwell, Arthur Spaulding (1969) The Conical Timbered Lodge on the Northwestern Plains: Historical, Ethnological, and Archaeological Evidence. Archaeology in Montana 10(4):1–49. :16–20; Moulton 1987 Moulton, Gary E. (editor) (1987) The Journals of the Lewis & Clark Expedition, vol. 4, April 7–July 27, 1805. University of Nebraska Press, Lincoln. :88, 202, 239; Voget 1977). The Central Rocky Mountains and Northwestern Plains contain abundant topographic references to ‘Teepee, Tipi, Wickiup, and Wigwam’ springs, creeks, draws, and canyons suggesting that abandoned wood structures were once located (and may still be found) in these vicinities. Anecdotal reports of wood lodges that no longer exist are relatively common and reinforce the notion of their widespread occurrence. For example, a conical pole structure similar to those at Pass Creek (24BE70) once existed near Elkhorn Hot Springs in the Pioneer Mountains near Dillon, Montana (Edith Palmer, personal communication 1996). This disjunction is likely due to inadequate archaeological sampling. Further, natural deterioration, wildfire, extensive livestock grazing, and vandalism since the turn of the twentieth century have undoubtedly contributed to the degradation and demise of many conical timber lodges, especially those located in easily accessible and well-used valley bottom and foothill settings. Conical lodge construction During their 1805 journey through the upper Missouri River basin, the Lewis and Clark expedition encountered numerous abandoned Indian timber lodges and brush shelters. On May 26, travelling westward between the Musselshell and Judith rivers, Meriwether Lewis commented ‘we have continued every day to pass more or less old stick lodges of the Indians in the timbered points, there are two even in the this little bottom where we lye’ (Moulton 1987 Moulton, Gary E. (editor) (1987) The Journals of the Lewis & Clark Expedition, vol. 4, April 7–July 27, 1805. University of Nebraska Press, Lincoln. :202). The expedition also ‘encamped in an old Indian stick lodge which afforded us a dry and comfortable shelter’ (Moulton 1987 Moulton, Gary E. (editor) (1987) The Journals of the Lewis & Clark Expedition, vol. 4, April 7–July 27, 1805. University of Nebraska Press, Lincoln. :263). Among early western travellers, the Lewis and Clark expedition provided one of the most complete ethnohistorical descriptions of a conical pole lodge, dated 4 May 1805: …the usual construction of the lodges we have lately passed is as follows. three or more strong sticks the thickness of a man's leg or arm and about twelve feet long are attached together at one end by a with of small willows, these are then set on one end and spread at the base, (to) forming a circle of ten twelve or 14 feet in diameter; sticks of driftwood and fallen timber of convenient size are now placed with one end on the ground and the other resting against those which are secured together at top by the with and which support and give the form to the whole, thus sticks are laid on until they make it as thick as they design, usually about three ranges, each piece breaking or filling up the interstice of the two beneath it, the whole forming a conic figure about 10 feet high with a small apperture in one side which answers as the door. leaves bark and straw are sometimes thrown over the work to make it more complete, but at best it affords a very imperfect shelter particularly without straw which is the state in which we have most usually found them (Moulton 1987 Moulton, Gary E. (editor) (1987) The Journals of the Lewis & Clark Expedition, vol. 4, April 7–July 27, 1805. University of Nebraska Press, Lincoln. :108–109). Exploring the Missouri River region in the early 1830s, Maximilian Prince of Weid remarked ‘round the trunk of an old tree the Indians had built a conical hut with pieces of wood; but for the whole voyage from Fort Union to Fort McKenzie, such huts were the only signs of human beings, and we did not see a single Indian’ (Thwaites 1906 Thwaites, Reuben Gold (editor)(1906) Early Western Travels 1784–1846, Part II of Maximilian, Prince of Weid's Travels in the Interior of North America, 1832–1834, volume XXIII, The Arthur H. Clark Company, Cleveland, Ohio. :55). Later western travelers (e.g. Cook et al. 1965:17; Kelly 1926 Kelly, Luther S. (1926) Yellowstone Kelly. Yale University Press, New Haven. :112, 130–134; Ross 1956:166) similarly described, though less explicitly, the wood huts, log shelters, and forts encountered on their travels. These ethnohistorical descriptions and the information later garnered from tribal informants by ethnographers provided a more complete picture of aboriginal shelter in the Central Rockies and Northwestern Plains. For example, Steward (1943:305–306) reported that among the Lemhi (Northern) Shoshone of east Idaho and southwest Montana, ‘conical houses’ were: built as winter dwellings; interlocked and/or tied at the intersection (foundation); covered with grass, tule, juniper bark, and brush placed in layers; entered by a doorway facing east; and had an interior fire hearth. Ewers’ (1944:183–184) description of the Blackfeet war lodge has become the stereotypic version of the Northwestern Plains conical timber lodge. Blackfeet war lodges were built of three interlocking foundation poles of about 3.6 m long. Willow poles, cottonwood bark, and brush were leaned, but not tied, against the outer poles to form a relatively weather-tight structure. Interior height was about 2.1 m and the lodge was just roomy enough to house a small war party sleeping at close quarters. Blackfeet lodges had low, angled, A-shaped, timber-covered entryways. Further east, in the Little Missouri River region of North Dakota, Bowers (1950 Bowers, Alfred (1950) Mandan Social and Ceremonial Organization. University of Chicago Press, Illinois. ) and Wilson (1928 Wilson, Gilbert L. (1928) Hidatsa Eagle Trapping. Anthropological Papers 30, Pt. 4. American Museum of Natural History, New York. ) described several Hidatsa and Mandan conical lodge variants. One lodge variant was built with a four-pole foundation, with poles, branches, and bark leaned against this superstructure. Brush, bark, and earth were then piled against the poles to a height of about 1 m for warmth and protection against enemy attack. A less substantially built grass-covered lodge was used when trapping in new territory (Bowers 1950 Bowers, Alfred (1950) Mandan Social and Ceremonial Organization. University of Chicago Press, Illinois. :232–233; Wilson 1928 Wilson, Gilbert L. (1928) Hidatsa Eagle Trapping. Anthropological Papers 30, Pt. 4. American Museum of Natural History, New York. :145, 411–414). Wilson (1928 Wilson, Gilbert L. (1928) Hidatsa Eagle Trapping. Anthropological Papers 30, Pt. 4. American Museum of Natural History, New York. :161) noted the close relationship between winter hunting and eagle trapping among the Hidatsa. Such ethnohistorical and ethnographic descriptions provide analogues for archaeological conical timber lodges (Wenker 1992 Wenker, Chris T. (1992) Native American Timber Structures of the Northwestern Plains. Archaeology in Montana 33(1):25–33. ; White and White 2012 White, David R. M., and Katharine L. White (2012) Wickiups of the Greater Yellowstone Ecosystem: Conical Timber Lodges within Bridger-Teton National Forest, Grand Teton National Forest, Shoshone National Forest, and Yellowstone National Park. National Park Service, Yellowstone Center for Resources, Yellowstone National Park, Wyoming. :38–56). While these descriptions are in general agreement with the archaeological record, many of the construction details vary. For example, outside of the Little Missouri River region, there is no clear preference for a three or four pole foundation in the extant conical lodge sample (Table 1). Of the 14 sites where the pole foundation was documented, eight exhibited a three-pole foundation while three have a four-pole foundation. However, for the majority of lodges the foundation type is undetermined probably due to the preservation condition and the fact that verification would require taking apart the structures in some cases. None of the identified lodges show evidence of hide, cordage, or rope used to tie the lodge foundation together. Nor do any have the covered A-shaped doorway as indicated by Ewers (1944 Ewers, John C. (1944) The Blackfoot War Lodge: Its Construction and Use. American Anthropologist 46:182–192.[Crossref], :184) for Blackfeet war lodges, including conical lodges currently known from central Montana in traditional Blackfeet territory. These various inconsistencies probably reflect the availability of on-site building material, terrain, lodge purpose, and use, as well as preservation circumstances and inconsistent documentation. Among the 46 conical lodges whose diameters were recorded, lodges range from less than a meter (32MZ435) to 9.1 m (24YE301), with a mean, mode, and range of 3.6, 3.4, and 8.3 m, respectively. Although function undoubtedly dictated size, the interior dimension of many conical lodge interiors fall within the same 5 to 10 m diameter range of a small-size tipi ring (Davis 1983 Davis, Leslie B. (1983) Stone Circles in the Montana Rockies: Relicit Households and Transitory Communities. In Microcosm to Macrocosm: Advances in Tipi Ring Investigation and Interpretation, edited by Leslie B. Davis, pp. 235– 278. Plains Anthropologist Memoir 19. :235–278, Table 18.5). Ethnographies indicate that lodge floors were often hollowed-out and covered with grass, brush, bark, mats, or hides (e.g., Steward 1943:272– 273). A depression where lodge 24BI1847 (Tipi Bottom) once stood near the Little Missouri River is suggestive of deliberate excavation (Allen 1983 Allen, Walter E. (1983) Eagle Trapping in the Little Missouri Badlands. North Dakota History Journal of the Northern Plains 50:4–22. :16). A partial bark floor was identified at the Evans site (24GV405) in central Montana (Joyes 1968 Joyes, Dennis (1968) The Evans Wickiup Site (24GV405). Archaeology in Montana 9(2):1–17. :9–10, Figure 5). At Big Sheep Creek Wickiup Cave in southwest Montana, rye grass (Elymus spp.) was used for bedding, and possibly as floor covering (Davis 1975 Davis, Carl M. (1975) Wickiup Cave. Plains Anthropologist 20:297– 305.[Taylor & Francis Online], :299). Grass matting was also noted at site 48BH719, the now vanished lodge located in a rockshelter in the Bighorn Mountains (Larson et al. 1975 Larson, T., P. Treet, and D. McGuire (1975) Wyoming Archaeological Site Form, Site Number 48BH719, Bureau of Land Management Little Mountain Survey. On file with the Wyoming State Historic Preservation Office, Laramie. ). Interior height measurements are typically compromised by the inward collapse of the pole lodge. However, 3.6 and 3.45 m are the mean and median size, respectively, for those 46 lodges where diameter measurements were taken or approximated. To the modern visitor, surviving lodges appear small and cramped for space, partly due to the steep pitch of the pole walls and their collapsed state. Nonetheless, Ewers (1944 Ewers, John C. (1944) The Blackfoot War Lodge: Its Construction and Use. American Anthropologist 46:182–192.[Crossref], ) described small war parties sleeping inside lodges for protection. In the current sample, lodge entrances face all directions. However, of the 38 lodges where doorway orientation was documented or estimated, approximately 70 percent of the lodge doorways are oriented towards the east and south (Tables 1 and 2). Kidwell's (1969:23) observation that conical lodges typically contained central or external fire hearths is not fully substantiated by the current lodge sample. Only 26 (40 percent) of the known sites contain evidence of interior or exterior hearths. However, where any amount of investigation has occurred, hearths and artifacts are invariably found in small quantities, such as the Evans (24GV405) (Joyes 1968 Joyes, Dennis (1968) The Evans Wickiup Site (24GV405). Archaeology in Montana 9(2):1–17. ) and Janich (24ML411) (Johnson et al. 1988 Johnson, Ann M., Kenneth J. Feyhl, Stuart Conner, and Michael Bryant (1988) The Cremation of two Early Historic Structures in the Bull Mountains. Archaeology in Mountain 29(2):97–115. ) sites, or in relative abundance such as at Big Sheep Creek Wickiup Cave (24BE601) (Davis 1975 Davis, Carl M. (1975) Wickiup Cave. Plains Anthropologist 20:297–305.[Taylor & Francis Online], ). At present, rather than focusing on a single trait such as the pole foundation or entryway, a combination of attributes may be the most useful way to characterize conical timber lodge construction and typology, including the number of lodges per site, pole procurement (dead versus live), extent of external covering, interior area, and presence of interior hearths and artifacts. Among the known conical lodges, the Lone Pine Peak (10CR1161), Pierce-Horton (10LH1222), Pass Creek (24BE70), Wickiup Cave (24BE601), Cottonwood Creek (24MA602), and Sheep Point 1 (48PA868) lodges are representative of apparently well-insulated structures built of vertical poles, bark, brush, rock, and earth. In contrast, lodges such as 48FR501 and 24GA325 were less substantially built and perhaps more lightly used, acknowledging that these sites are not thoroughly investigated. As discussed further below, the former may indicate seasonal residences or domiciles while the latter were built as war lodges, hunting camps, or for other special purposes. Antiquity of conical lodges The chronological age of most conical timber lodges is currently unknown. Dating has been hampered by the fragility of the wood structures, apparent lack of artifacts and datable features, and minimal investigation. No radiocarbon dates are available among the current conical lodge sample. Dendrochronological dating has been successful at several lodge sites. At the Evans site (24GA405) in central Montana, the growth pattern of cored poles led the investigators to conclude that the lodge was built ‘not far from 1865’ (Joyes 1968 Joyes, Dennis (1968) The Evans Wickiup Site (24GV405). Archaeology in Montana 9(2):1–17. :10). This historic age was supported by glass beads and the barrel of a Northwest Gun excavated from within the lodge interior. The investigators concluded that the latter was mounted and proofed in the late 1850s (Grey 1968 Grey, Don (1968) The Northwest Gun from the Evans Site. Archaeology in Montana 9(2):11–17. :15). In addition, metal axe marks were observed on the butt end of the poles. The Soapy Dale Peak Lodge (48HO107) in the Absaroka Range in Wyoming was cored in the mid 1980s (Reher et al. 1985). Increment cores and slabs were removed from the standing lodge and surrounding mixed conifer-deciduous forest. The aspen and lodgepole pine samples from the lodge poles were long enough for cross-dating. However, they required a slight (seven to eight year) upward adjustment to account for the lag effect in aspen growth (due to fluctuating water tables in the aspen grove area) and match corresponding peaks in core sequences from the surrounding forest and other increment bore stations in the Absaroka Range (Reher et al. 1985:21–23). Four of the five pole samples clustered from A.D. 1852 to A.D. 1862, with the single outlier dating to 1848. The researchers concluded that the structure was built sometime immediately after A.D. 1865. Napton (1966 Napton, Lewis K. (1966) Canyon and Valley: Preliminary Archaeological Survey of the Gallatin Area, Montana. Unpublished Master's thesis, Department of Anthropology, University of Montana, Missoula. :137–143) cored several poles and nearby living trees at the Snowflake Pole lodge (24GA325) in southwest Montana, but the dates have not been published. Despite the use of old deadfall in lodge construction, the potential for complacent or compressed growth rings in some environments (Speer 2010 Speer, James H. (2010) Fundamentals of Tree-Ring Research. The University of Arizona Press, Tucson. :22–23), and other dating challenges, dendrochronology remains an important research tool in conical lodge studies. Cultural materials found inside and outside of all investigated conical lodges date exclusively to the Protohistoric and Historic periods in the Northwestern Plains and intermountain chronologies (Frison 1991). The Wickiup Cave (24BE601) site in Montana and the Boulder Ridge site (48PA2642) in Wyoming yielded a variety of stone, glass, metal, pottery, and perishable items (Davis 1975 Davis, Carl M. (1975) Wickiup Cave. Plains Anthropologist 20:297–305.[Taylor & Francis Online], ; Scheiber and Finley 2010 Scheiber, Laura L., and Judson Byrd Finley (2010) Mountain Shoshone Technological Transitions Across the Great Divide. In Across the Great Divide: Culture Contact and Culture Change in North America at AD 1500, edited by L. L. Scheiber, and M. Mitchell, pp. 128–148. University of Arizona Press, Tucson. ). The Evans Wickiup site (24GV405) yielded metal and glass items (Joyes 1968 Joyes, Dennis (1968) The Evans Wickiup Site (24GV405). Archaeology in Montana 9(2):1–17. ). Postfire excavations at the Janich lodge (24ML411) produced several gun flints, lead balls, glass beads, and brass tacks, indicating a mid-nineteenth century date for this site (Johnson et al. 1988 Johnson, Ann M., Kenneth J. Feyhl, Stuart Conner, and Michael Bryant (1988) The Cremation of two Early Historic Structures in the Bull Mountains. Archaeology in Mountain 29(2):97–115. ). A single side-notched arrowpoint recovered near a lodge at 48SH575 in the Bighorn Mountains also possibly indicates a Protohistoric to Historic period age. The age of conical lodges may also be generally inferred from their preservation condition. In the Central Rocky Mountains, elevation, temperature, moisture, worms, insects, bacteria, and fungus contribute to the decomposition of dead woody material and duff (Schoennagel et al. 2004 Schoennagel, Tania, Thomas T. Verblen, and William H. Romme (2004) The Interaction of Fire, Fuels, and Climate across Rocky Mountain Forests. BioScience 54(7):661–676.[Crossref], [Web of Science ®], ). Thus, the decomposition rates of woody debris in forested environments serve as a proxy measure of the natural decay rate of conical lodge poles, recognizing that local conditions influence preservation. For example, the decomposition rate of the Douglas fir (P. menziesii) boles, a common tree species used in conical lodge construction, is approximately 300 years (Means et al. 1985 Means, Joseph E., Kermit Cromack, Jr., and Paul C. MacMillan (1985) Comparison of Decomposition Models Using Wood Density of Douglas-fir Logs. Canadian Journal of Forestry Research 15:1092–1098.[Crossref], [Web of Science ®], ). Thus, through the aforementioned biological processes, lodges made of live or deadfall Douglas fir would disintegrate over three centuries or less in forested environments. The bases of their vertical poles slowly rotted and splintered, resulting in both the downward and (usually) inward collapse of the structure and, eventually, an inconspicuous pile of poles. The Pass Creek conical lodges (24BE70) in Montana and the Painter Gulch (48PA305) lodges in Wyoming are examples of this disintegration process. Site 24BE1211 in the Tendoy Mountains, first recorded in 1985, is composed of three separate ‘short and squat’ lodges composed of locally available Douglas fir (Kingsbury 1986 Kingsbury, Lawrence A. (1986) Wickiup Protection Project. Unpublished manuscript, Bureau of Land Management, Butte District, Montana. :12– 13). These lodges were barely recognizable to me in the summer of 2011, indicating the rate of deterioration over the past several decades. Wildfire frequency provides another preservation threshold for conical timber lodges. In the Central and Northern Rocky Mountains, fire disturbance intervals are as infrequent as 500 years to as frequent as 40 years in warm, mesic Douglas fir and lower subalpine lodgepole pine vegetation communities where many conical timber lodges are located (Brown 2000 Brown, James K. (2000) Introduction and Fire Regimes. In Wildland Fire in Ecosystems: Effects of Fire on Flora, edited by James K. Brown, and Jane Kapler Smith, pp. 1–7. USDA Forest, General Technical Report RMRS-GTR-42-Volume 2. Forest Service Rocky Mountain Research Station, Fort Collins, Colorado. ). The mean interval of mixedseverity and stand-replacement fires in a Douglas fir forest is 65 and 170 years, respectively (Fryer and Luensmann 2012 Fryer, Janet L., and Peggy S. Luensmann (2012) Fire regimes of the conterminous United States. http://www.fs.fed.us.ezproxy.lib.utah.edu/database/feis/fire_regime_table/PNVG_fire_regime_table.html, accessed June 11, 2012. :7–8). In subalpine lodgepole pine forest, the mean interval of mixed-severity and stand-replacement fires is 450 and 170 years, respectively (Fryer and Luensmann 2012 Fryer, Janet L., and Peggy S. Luensmann (2012) Fire regimes of the conterminous United States. http://www.fs.fed.us.ezproxy.lib.utah.edu/database/feis/fire_regime_table/PNVG_fire_regime_table.html, accessed June 11, 2012. :7–8; Lotan et al. 1985 Lotan, James E., James K. Brown, and Leon F. Neuenschwander (1985) Role of Fire in Lodgepole Pine Forests. In Lodgepole Pine: The Species and its Management Symposium Proceedings, edited by D. M. Baumgartner, R. G. Krebill, J. T. Arnott, and C. F. Weetman, pp. 133–152. Washington State University, Pullman. :139–141). Fire frequency and severity are influenced by forest type and structure, fuels loading, weather conditions, climate patterns, and human activity (Schoennagel et al. 2004 Schoennagel, Tania, Thomas T. Verblen, and William H. Romme (2004) The Interaction of Fire, Fuels, and Climate across Rocky Mountain Forests. BioScience 54(7):661–676.[Crossref], [Web of Science ®], ). Nonetheless, these data show that mixed-severity and stand-replacement wildfire in the Central Rocky Mountains have reduced many conical lodges (and other archaeological wood features) to ashes over the last 400 years. The vulnerability of conical lodges to wildfire was likely contingent on the environmental setting. For example, lodges in open meadows or riparian areas (such as Lava Creek, 48YE2) or protected in rockshelters (such as Wickiup Cave, 24BE601) would have had a (slightly) better chance of survival from mixed-severity wildfire than those in a dense forest. Further, fires started by lightning or by native peoples to enhance local food gathering areas, clear trails, or promote game and/or horse forage possibly created ‘fuel breaks’ that protected and prolonged the life of some wood lodges (Barrett and Arno 1999 Barrett, Stephen W., and Stephen F. Arno (1999) Indian Fires in the Northern Rockies: Ethnohistory and Ecology. In Indians, Fire and the Land in the Pacific Northwest, edited by Robert T. Boyd, pp. 50–64. Oregon State University Press, Corvallis. ). In any event, concerted wildfire suppression, forest fuels accumulation, insect infestation and disease, and climate change since the turn of the twentieth century have led to ecological conditions that today put all surviving conical lodges and other perishable wood features at high risk (Dale et al. 2001 Dale, Virginia H., Linda A. Joyce, Steve McNulty, Ronald P. Neilson, Matthew P. Ayres, Michael D. Flannigan, Paul J. Hansen, Lloyd C. Irland, Ariel E. Lugo, Chris J. Peterson, Daniel Simberloff, Frederick J. Swanson, Brian J. Stocks, and B. Michael Wotton (2001) Climate Change and Forest Disturbance. Bioscience 51:723–734.[Crossref], [Web of Science ®], ). In sum, forestry decomposition rate and fire frequency models provide broad preservation thresholds of approximately 300 to 400 years for wood lodges located in Central Rocky Mountain forests. Dendrochronology and archaeological evidence indicate that most surviving lodges date significantly later to the nineteenth century. These data should not imply that conical lodges were solely a product of the Protohistoric or Historic periods. Rather, as previously discussed, older lodges have disappeared through various natural processes and their earlier presence may only now be detected as surface or buried archaeological materials, as attested by the Boulder Ridge site (48PA2642) in the Absaroka Mountains of northwest Wyoming. Use patterns The use of conical timber structures as war lodges is widely documented in the ethnohistorical literature. That conical lodges represent war lodges was fostered by the observations of Grinnell (1901 Grinnell, George Bird (1901) The Lodges of the Blackfeet. American Anthropologist 3:650–688.[Crossref], ), Schultz (1907 Schultz, James Willard (1907) My Life as an Indian: The Story of a Red Woman and a White Man in the Lodges of the Blackfeet. Doubleday, Page & Company, New York. ), Kelly (1926 Kelly, Luther S. (1926) Yellowstone Kelly. Yale University Press, New Haven. ), Russell (Haines 1955 Haines, Aubrey L. (editor) (1955) Journal of a Trapper (1834–1843), by Osborne Russell. University of Nebraska Press, Lincoln. ), Bourke (1971 Bourke, John G. (1971) [1891] On the Border with Crook. Charles Scribner's Sons., New York. 1971 fascimile ed. University of Nebraska Press, Lincoln. ), and other frontiersmen, military officers, and travelers, and perpetuated and expanded by anthropologists Ewers (1944 Ewers, John C. (1944) The Blackfoot War Lodge: Its Construction and Use. American Anthropologist 46:182–192.[Crossref], , 1958), Kidwell (1969 Kidwell, Arthur Spaulding (1969) The Conical Timbered Lodge on the Northwestern Plains: Historical, Ethnological, and Archaeological Evidence. Archaeology in Montana 10(4):1–49. ), Malouf (1963 Malouf, Carling (1963) Battle Pits and War Lodges. Archaeology in Montana 2(5):1–11. Missoula. ), Des Rosier (1965 Des Rosier, Fred L. (1965) Kutenai War Lodges. Archaeology in Montana 6(1):14. ), Voget (1971), and others. For the Blackfeet, Ewers (1944 Ewers, John C. (1944) The Blackfoot War Lodge: Its Construction and Use. American Anthropologist 46:182–192.[Crossref], , 1958) provided construction details and accounts of their use in horse-raiding and warfare. Poles, pine bough, and brush war lodges were built in heavily timbered or secluded areas, usually near water, within one or two days journey from the enemy camp. Tightly enclosed lodges thus offered shelter from the elements, contained campfire smoke and light, served as a supply base, and provided defensive protection during surprise attacks (Ewers 1958:130–132). Bigger lodges or multiple lodges were built to accommodate large war parties. War lodge entrances were strategically located so that warriors could escape or defend against a surprise attack. The Crow made sturdy conical-shaped war lodges from cottonwood and pine poles, often braced against a standing tree (Lowie 1922:261–262; Voget 1977 Voget, Fred W. (1977) Timber Shelters of the Crow Indians. Archaeology in Montana 18(2–3):1–18. :43). The Cheyenne, Cree, Hidatsa, and most Plains Indian bands built temporary timber shelters while on the warpath, primarily during the winter months (Denig 1930:554; Grinnell 1924:49–50; Teit 1930:359). Ewers (1944 Ewers, John C. (1944) The Blackfoot War Lodge: Its Construction and Use. American Anthropologist 46:182–192.[Crossref], :189–190), Lowie (1922:259), and others suggest that the locations of timber shelters were generally known by band members and allies, resulting in their repair, salvage, and reuse. They were abandoned when discovered by enemies. The protective value of pole war lodges against gunfire varied, as Osborne Russell's grim narrative of a fight between the Blackfeet and white trappers attests (Haines 1955 Haines, Aubrey L. (editor) (1955) Journal of a Trapper (1834–1843), by Osborne Russell. University of Nebraska Press, Lincoln. :52). Not all war lodges were built of vertical timbers. The Crow and Shoshone inserted willow branches in the ground in a semi-cylindrical shape and then covered them with blankets or canvas for warmth (Bourke 1971 Bourke, John G. (1971) [1891] On the Border with Crook. Charles Scribner's Sons., New York. 1971 fascimile ed. University of Nebraska Press, Lincoln. :301–302, 340). Increased tribal militarism, horse raiding, and warfare during the Protohistoric and Historic periods apparently accelerated the construction of conical lodges, cribbed and truncated log structures, forts, breastworks, and corrals (Voget 1977 Voget, Fred W. (1977) Timber Shelters of the Crow Indians. Archaeology in Montana 18(2–3):1–18. :10–11). It is worth noting that not all brush and log structures can be attributed to Indian bands since trapping brigades, military expeditions, and western travelers also built structures as shelter, to corral livestock, and to defend against Indian attacks (e.g., Leonard 1904 Leonard, Zenas (1904) Adventures of Zenas Leonard Fur Trader and Trapper 1831–1836, edited by W.F. Wagner The Burrows Brothers Company, Cleveland, Ohio. :70, 262). In any case, the archaeological evidence of weaponry of any kind is rare among the known conical lodge sites (or other wood features), with the exception of the rifle barrel recovered at the Evans lodge (24GV405) and gun flints and lead balls at the Janich site (24ML411) in central Montana (Joyes 1968 Joyes, Dennis (1968) The Evans Wickiup Site (24GV405). Archaeology in Montana 9(2):1–17. ). Further, the presence of weapons or weapon parts need not automatically imply raiding and warfare since they were also used for hunting and personal protection. In addition to their role in the Plains war complex, conical timber lodges served utilitarian and religious purposes, including hunting, cooking, hide preparation, elopement, eagle trapping, healing, mourning, menstruation, and sweats (Bowers 1950 Bowers, Alfred (1950) Mandan Social and Ceremonial Organization. University of Chicago Press, Illinois. :206; Bushnell 1922 Bushnell, David I. Jr. (1922) Villages of the Algonquian, Siouan, and Caddoan Tribes West of the Mississippi.

Sturtevant, general editor, Smithsonian Institution, Washington, DC. :614, Figure 7; Grinnell 1919; Lowie 1909 Lowie, Robert H. (1909) The Northern Shoshone. Anthropological Papers of the American Museum of Natural History Papers 2(2):169– 303. :183, 1983:89–90; Mandelbaum 1940 Mandelbaum, David G. (1940) The Plains Cree. Anthropological Papers of the American Museum of Natural History, 37(2):153–316. :212; Steward 1943:272–274). Wood shelters were constructed by band members who were unable to obtain sufficient hides for a skin-covered lodge (Steward 1943:272; Voget 1977 Voget, Fred W. (1977) Timber Shelters of the Crow Indians. Archaeology in Montana 18(2–3):1–18. :9–10). Conical lodges built as emergency shelters, particularly in mountain environments, are called ‘storm huts’ among the Blackfeet people (Maria Zedeño, personal communication 2013). These Blackfeet structures typically consisting of a dozen tree branches arranged in a circular shape were built by hunters and warriors, and at certain task camps. In a similar vein, Bies (2011 Bies, Michael T. (2011) Conical Pole Lodges and Possible Prehistoric Travel Routes. Paper presented at the 10th Biennial Rocky Mountain Anthropological Conference, Missoula, Montana. ) hypothesized that conical lodges in the Absaroka Range were used as expedient shelters (storm huts?) built adjacent to a mountain travel route. The domestic and utilitarian functions of conical timber lodges are difficult to prove from the existing archaeological evidence with a few exceptions such as Big Sheep Creek Wickiup Cave (Davis 1975 Davis, Carl M. (1975) Wickiup Cave. Plains Anthropologist 20:297–305.[Taylor & Francis Online], ). The density, diversity, and patterning of faunal remains, hearth features, tools, and other debris within and outside the structure may eventually help to gain an understanding of some lodges and the behavioral contexts in which they were built and used. Based on robust ethnographic evidence, Allen (1983 Allen, Walter E. (1983) Eagle Trapping in the Little Missouri Badlands. North Dakota History Journal of the Northern Plains 50:4–22. ) documented the association of archaeologically known conical lodges in western North Dakota with eagle trapping among the Plains Village Tradition Arikara, Hidatsa, and Mandan who laid claim to trapping rights along the length of the Little Missouri River. Lodge selection was strongly predicated by the location of eagle trapping pits, usually at the crest of ridges and steep badland escarpments (Allen 1983 Allen, Walter E. (1983) Eagle Trapping in the Little Missouri Badlands. North Dakota History Journal of the Northern Plains 50:4–22. :8–12). The surviving conical timber lodges are estimated to post-date A.D. 1880. The age of some pits likely extended further back in time. Lodges were considered sacred when the eagle hunting bundle or a bison skull altar was placed inside. Conical lodges alternated as winter hunting shelters in the Little Missouri River badlands (Allen 1983 Allen, Walter E. (1983) Eagle Trapping in the Little Missouri Badlands. North Dakota History Journal of the Northern Plains 50:4–22. :5). It is unclear if the lodges were well concealed as a ceremonial requirement or if for protection from Dakota (Sioux) or other enemies. Conical lodges also served various utilitarian functions associated with the occupation of winter earth lodge villages (Bowers 1965:58–59; Parks 2001 Parks, Douglas R. (2001) Arikara. In Plains, edited by Raymond J. DeMallie, pp. 695–717. Handbook of North American Indians, Vol. 13, William C. Sturtevant, general editor, Smithsonian Institution, Washington, DC. :368). Voget's (1977:6–7) Hidatsa informant reported that his people built conical lodges along the Little Missouri River to escape eighteenth and nineteenth-century smallpox epidemics. In the Great Basin, Shoshone bands built structures (wickiups) of willow, pole, brush, tule, bark, earth, and rock (O'Connell and Erickson 1974 O'Connell, James F., and Jonathan E. Erickson (1974) Earth Lodges to Wickiups: A Long Sequence of Domestic Structures from the Northern Great Basin. In A Collection of Papers on Great Basin Archaeology, edited by Robert Elston, and Loretta Sabini, pp. 43– 61. Nevada Archaeological Research Papers No. 5, University of Nevada, Reno. ; Steward 1943:272– 273, 305–309). In the Central Rocky Mountains and adjacent Northwestern Plains, the conical timber lodge was apparently the mountain/plains equivalent of the Great Basin wickiup built by Numic (Shoshone) peoples who had migrated into this region. The single conical lodge in Wickiup Cave (24BE601) in southwest Montana appears to have served as a domestic residence (Figures 2 and 3) where several or more individuals slept on beds of boughs and grasses inside a large lodge (Davis 1975 Davis, Carl M. (1975) Wickiup Cave. Plains Anthropologist 20:297–305.[Taylor & Francis Online], :299). An abundance of artifacts, including Intermountain Ware pottery, was interpreted to indicate a seasonal camp occupied by a Mountain (Tukidika, Sheep Eater) Shoshone family during the Protohistoric or Historic period (Davis 1975 Davis, Carl M. (1975) Wickiup Cave. Plains Anthropologist 20:297–305.[Taylor & Francis Online], :304–305). As previously described, a conical lodge was completely consumed by a 2003 wildfire in the Absaroka Mountains of northwest Wyoming (Eakin 2005 Eakin, Daniel H. (2005) Evidence for Shoshonean Bighorn sheep Trapping and Early Historic Occupation in the Absaroka Mountains of Northwest Wyoming. University of Wyoming National Park Service Research Center 29th Annual Report 2005, pp. 74–86. University of Wyoming, Laramie. ). Detailed mapping of fire-exposed artifacts revealed distinct bone scatters, knapping areas, stone tools, ceramics, metal, and glass artifacts probably representing a (Mountain) Shoshone occupation (Scheiber and Finely 2010). For aboriginal bands such as the Shoshone who occupied eastern Idaho, southwest Montana, and northwest Wyoming in the nineteenth century, conical timber lodges probably provided shelter better suited to mountain environments. Tipis required numerous hides which would have been difficult to obtain, maintain, and transport on mountain trails, especially by pedestrian bands using dog travois (Loendorf and Stone 2006 Loendorf, Larry, and Nancy Medaris Stone (2006) Mountain Spirit: The Sheep Eater Indians of Yellowstone. University of Utah Press, Salt Lake City. :103–110; Voget 1977 Voget, Fred W. (1977) Timber Shelters of the Crow Indians. Archaeology in Montana 18(2–3):1–18. :9). For hunting and war parties on the move, hide tipis were impractical, necessitating only expediently constructed wood pole, cribbed log, or brush and willow lodges, at least in the winter months. As discussed by Seymour (2009 Seymour, Deni J. (2009) Nineteenth-century Apache Wickiups: Historically Documented Models for Archaeological Signatures of the Dwellings of Mobile People. Antiquity 83:157–164.[Crossref], [Web of Science ®], :162) for Apache wickiups, the shelters of mobile hunter-gatherers were not intended to contain all activities associated with our contemporary conception of dwellings. Whether located in mountain, foothills, plains, or basin environments, many basic activities were carried on outside of the shelter for reasons of space, comfort, shade, sanitation, and safety. Enclosed shelters provided ‘secluded space for sleeping, privacy, storage, corralling children, and protection from the elements’ (Seymour 2009 Seymour, Deni J. (2009) Nineteenth-century Apache Wickiups: Historically Documented Models for Archaeological Signatures of the Dwellings of Mobile People. Antiquity 83:157–164.[Crossref], [Web of Science ®], :162). Thus, pole lodges were augmented by exterior work spaces and other temporary structures, as was in evidence at the Boulder Ridge site (48PA2642) in northwest Wyoming (Scheiber and Finley 2010 Scheiber, Laura L., and Judson Byrd Finley (2010) Mountain Shoshone Technological Transitions Across the Great Divide. In Across the Great Divide: Culture Contact and Culture Change in North America at AD 1500, edited by L. L. Scheiber, and M. Mitchell, pp. 128–148. University of Arizona Press, Tucson. ). The surrounding landscape may be as important to understanding conical timber lodge age, function, use, and cultural association as the lodge itself. Cultural association The Central Rocky Mountains and Northwestern Plains are characterized by complex aboriginal histories during the late eighteenth and nineteenth centuries. The candidate list of conical lodge builders in these regions is therefore long and, at minimum, includes Arapaho, Arikara, Assiniboine-Gros Ventre, Bannock, Blackfeet, Cree, Cheyenne, Chippewa, Coeur d'Alene, Crow, Hidatsa, Kiowa, Kootenai, Nez Perce, Salish, Shoshone, Sioux, and Ute (e.g., Denig 1930; Ewers 1958; Grinnell 1924; Janetski 1987 Janetski, Joel C. (1987) The Indians of Yellowstone Park. Bonneville Books, University of Utah Press, Salt Lake City. ; Liljeblad 1972 Liljeblad, Sven (1972) The Idaho Indians in Transition, 1805–1960. Special Publication of the Idaho State University Museum, Pocatello. ; Lowie 1909 Lowie, Robert H. (1909) The Northern Shoshone. Anthropological Papers of the American Museum of Natural History Papers 2(2):169–303. ; Nabokov and Loendorf 2004 Nabokov, Peter, and Lawrence Loendorf (2004) Restoring a Presence: American Indians and Yellowstone National Park. University of Oklahoma Press, Norman. ). The number of interlocking foundation poles has been viewed by archaeologists as a way to potentially infer cultural association based on comparisons with the ethnographic record of pole tipi construction, as previously discussed (Wenker 1992 Wenker, Chris T. (1992) Native American Timber Structures of the Northwestern Plains. Archaeology in Montana 33(1):25–33. [Google Scholar]; White and White 2012 White, David R. M., and Katharine L. White (2012) Wickiups of the Greater Yellowstone Ecosystem: Conical Timber Lodges within Bridger-Teton National Forest, Grand Teton National Forest, Shoshone National Forest, and Yellowstone National Park. National Park Service, Yellowstone Center for Resources, Yellowstone National Park, Wyoming. [Google Scholar]). Such correlations have thus far proven ambiguous. For example, the four-pole foundation ethnographically ascribed to the Northern Shoshone lodges does not match the conical lodge foundations at Wickiup Cave nor the Pass Creek sites in southwest Montana, although a Shoshone presence is well documented at both sites (Davis 1975 Davis, Carl M. (1975) Wickiup Cave. Plains Anthropologist 20:297–305.[Taylor & Francis Online], [Google Scholar]; Davis and Scott 1987 Davis, Carl M., and Sara A. Scott (1987) The Pass Creek Wickiups: Northern Shoshone Hunting Lodges in Southwest Montana. Plains Anthropologist 32:83–92.[Taylor & Francis Online], [Google Scholar]; Wenker 1992 Wenker, Chris T. (1992) Native American Timber Structures of the Northwestern Plains. Archaeology in Montana 33(1):25–33. [Google Scholar]:9–10). In fact, ethnographies may not fully account for variability in pole lodge construction. Further, hide and pole tipi and conical lodge construction may not be directly analogous given the different materials used in their fabrication. Conical lodges scattered throughout the mountain ranges and basins of Montana and Wyoming were the shelters of different, often widely travelled, tribal groups engaged in hunting, horse raiding, and sometimes warfare in enemy territory. The ethnohistorical and ethnographic evidence for Blackfeet and Crow use of timber shelters as war lodges is compelling but other tribes followed suite, especially as horse-raiding and military action increased throughout the Protohistoric and Historic periods (Binnema 2001 Binnema, Theodore (2001) Common & Contested Ground: A Human and Environmental History of the Northwestern Plains. University of Oklahoma Press, Norman. [Google Scholar]:129–197; McGinnis 1990 McGinnis, Anthony (1990) Counting Coup and Cutting Horses: Intertribal Warfare on the Northern Plains 1738–1889. Cordillera Press, Evergreen, Colorado. [Google Scholar]:35–47). As a consequence of this fluid historical situation, associating a specific conical lodge with a specific tribal group is nearly impossible without collaborating archaeological, informant, or ethnohistorical evidence. The tribal informants in the YNP study were unable to associate a known conical lodge or lodge style with a specific tribal group (White and White 2012 White, David R. M., and Katharine L. White (2012) Wickiups of the Greater Yellowstone Ecosystem: Conical Timber Lodges within Bridger-Teton National Forest, Grand Teton National Forest, Shoshone National Forest, and Yellowstone National Park. National Park Service, Yellowstone Center for Resources, Yellowstone National Park, Wyoming. [Google Scholar]:59–62). In one rare example of a documented cultural association, a Northern (Lemhi) Shoshone family group from the Lemhi Reservation in Idaho used several conical pole lodges at Pass Creek (24BE70) early in the twentieth century, according to a local rancher on whose property the Indians were partially encamped (Davis and Scott 1987 Davis, Carl M., and Sara A. Scott (1987) The Pass Creek Wickiups: Northern Shoshone Hunting Lodges in Southwest Montana. Plains Anthropologist 32:83– 92.[Taylor & Francis Online], [Google Scholar]:89–91). In fact, conical timber lodges in southwest Montana, northwest Wyoming and east Idaho are frequently attributed to Shoshone bands based on a wealth of Shoshone historical and ethnographic evidence (Dominick 1964 Dominick, David (1964) The Sheep Eaters. Annals of Wyoming 36(2):231–268. [Google Scholar]; Hultkrantz 1961 Hultkrantz, Ake (1961) The Shoshones in the Rocky Mountain Area. Annals of Wyoming 33(1):19–41.

[Google Scholar]). However, throughout the turbulent Protohistoric and Historic periods this region was inhabited and travelled by various Plains and intermountain Indian bands who may (or may not) have built timber structures for shelter or other various purposes. The origin of the conical timber lodge is speculative. As one of the simplest forms of human shelter, conical pole and brush lodges probably did not originate in a specific region or cultural area, or with a specific cultural group (Faegre 1980 Faegre, Torvald (1980) Tents: Architecture of Nomads. Anchor Books, Garden City. [Google Scholar]). A northeastern woodlands-boreal forest derivation was nonetheless proposed by Wissler (1910 Wissler, Clark (1910) Material Culture of the Blackfoot Indians. Anthropological Papers 5, Pt. 1. American Museum of Natural History, New York. [Google Scholar]:117) based on the prevalence of pole, bark, and thatch wigwams and pole houses in that region. His narrative suggested that native people migrating to the Great Plains relied on an array of wood shelter types. Once the pole and hide tipi came into wide use on the Plains in the late fifteenth or early sixteenth centuries as part of a nomadic economy, traditional wood shelters of whatever type quickly gave way to more adaptable and transportable pole and hide tipis (Brasser 1982 Brasser, Ted J. (1982) The Tipi as an Element of the Emergence of Historic Plains Indian Nomadism. Plains Anthropologist 27:309– 321.[Taylor & Francis Online], [Google Scholar]:310–311). Expanding on this concept, Ewers (1944 Ewers, John C. (1944) The Blackfoot War Lodge: Its Construction and Use. American Anthropologist 46:182–192.[Crossref], [Google Scholar]:191) considered the Blackfeet war lodge to be a specialized form of a tipi. In contrast, Voget (1977 Voget, Fred W. (1977) Timber Shelters of the Crow Indians. Archaeology in Montana 18(2–3):1–18. [Google Scholar]:11) argued that timber shelter construction was primarily a Historic period phenomenon on the Northwestern Plains, precipitated by prolonged winter warfare, an increase in the number and frequency of war parties, and the need for both defensive protection against gunfire and security to shelter horses and booty. The abundance of conical lodges, cribbed log structures, and defensive breastworks apparently dating to the Protohistoric and Historic periods lends tentative support to Voget's hypothesis, although it discounts preservation factors (Wenker 1992 Wenker, Chris T. (1992) Native American Timber Structures of the Northwestern Plains. Archaeology in Montana 33(1):25–33. [Google Scholar]:23). Complicating matters, the neighboring eastern Great Basin has its own deep history of pole, thatch, and brush shelter construction unrelated to the Eastern Woodlands or the Northwestern Plains (O'Connell and Erickson 1974 O'Connell, James F., and Jonathan E. Erickson (1974) Earth Lodges to Wickiups: A Long Sequence of Domestic Structures from the Northern Great Basin. In A Collection of Papers on Great Basin Archaeology, edited by Robert Elston, and Loretta Sabini, pp. 43–61. Nevada Archaeological Research Papers No. 5, University of Nevada, Reno. [Google Scholar]). Shoshone bands migrating from this region into the mountains and valleys of east-central Idaho, southwest Montana, and northwest Wyoming adapted this Great Basin housing style. These typically sturdier structures are now termed conical timber lodges by archaeologists. In this regard, dating of the Numic expansion into the Central Rocky Mountains and Northwestern Plains is controversial, potentially involving multiple migrations ranging in date between 200 and 2,000 years ago, if not significantly earlier (Aikens and Witherspoon 1986 Aikens, C. Melvin, and Younger T. Witherspoon (1986) Great Basin Prehistory: Linguistics, Archaeology, and Environment. In Anthropology of the Desert West Essays in Honor of Jesse D. Jennings, edited by Carol J. Condie, and Don D. Fowler, pp. 7–20. University of Utah Anthropological Papers Number 110, University of Utah Press, Salt Lake City.

[Google Scholar]) think that a surviving Mountain Shoshone tradition on the Yellowstone Plateau, as observed by early western travelers and YNP managers, was prompted by Euroamerican expansion and is the consequence of pushing an indigenous people to the margins. In any case, the conical timber lodge was adapted to the mountain and plains by Numic peoples. At present, a single, albeit tentative, interpretation may accommodate these differing perspectives. Conical timber lodges have a long history on the Northwestern Plains, whatever their ultimate origin. Archaic and Late Prehistoric period house features, demarcated by post holes, depressions and pits, indicate familiarity with wood structural elements (e.g., Frison 1971 Frison, George C. (1971) Shoshonean Antelope Procurement in the Upper Green River Basin, Wyoming. Plains Anthropologist 15:258–284. [Google Scholar]:259–260; Harrell et al. 1997 Harrell, Lynn L., Hoefer Ted, III, and Scott T. McKern (1997) Archaic Housepits in the Wyoming Basin. In Changing Perspectives on the Archaic of the Northwest Plains and Rocky Mountains, edited by Mary Lou Larson, and Julie E. Francis, pp. 334– 367. University of South Dakota Press, Vermillion. [Google Scholar]). It may be inferred that simply constructed, vertical pole and brush shelters complimented the use of pit houses, cribbed log structures, and pole-hide tipis throughout much of the Northwestern Plains prehistory for the cultural uses previously described. During the Late Prehistoric through Protohistoric periods, Shoshone bands migrating into the Central Rockies adopted the conical timber lodge as a form of housing in mountain and foothill environments. Lastly, during the Protohistoric and Historic periods, wood structures (war lodges, breastworks, and corrals) proliferated in response to intensified raiding and warfare across the Northwestern Plains, as posited by Ewers (1944 Ewers, John C.

This long and overlapping history of pole and brush shelter use has been obscured by the poor survival rate of wood ruins, lack of timely and systematic field investigation, and research frameworks that do not fully integrate the range of shelter types and housing once used by mobile hunter-gatherers across this region. Conclusion A total of 92 conical timber lodge sites are currently recorded on the Northwestern Plains and in the Central Rocky Mountains. This total number would likely change with more concerted conical lodge survey and investigation. The majority of lodges are located in southwest Montana and northwest Wyoming. Whether this distribution reflects archaeological sampling, preservation conditions, or cultural factors is unclear. The strong clustering of conical lodges (and other wood features) in east Idaho, southwest Montana, and northwest Wyoming seems to point to Shoshone and Crow bands who inhabited this mountainous region during the Protohistoric and Historic periods. These perishable archaeological features are in varying states of preservation, with many on the verge of collapse or complete disintegration. While forestry decomposition models and fire frequency studies provide generous preservation thresholds of 300 to 400 years for wood features in the Central Rocky Mountains, most surviving conical lodges probably date to the nineteenth century, based on dendrochronological and archaeological evidence from a handful of lodge sites. Ethnohistorical and ethnographic evidence, and to a lesser extent archaeological data, indicate that conical timber lodges functioned in a variety of ways over a vast geographic area to accommodate the diverse cultural needs of native peoples. The traditional interpretation that conical timber lodges were predominantly built for raiding and warfare probably reflects a gender bias towards better documented, more dramatic and visible, male-dominated activities at the expense of mundane domestic and utilitarian functions. At this juncture, the archaeological evidence for war lodges is no more compelling than for other uses. As a heuristic model, conical lodge distribution and function may be presently regarded as follows. On the eastern periphery of the Northwestern Plains, along the Little Missouri River and its tributaries, conical lodges served a ceremonial role in eagle trapping among the Hidatsa, Mandan, Arikara, and other Middle Missouri groups. Where located near prime eagle trapping sites, lodges were intensively used and frequently rebuilt. When not used for eagle trapping, these same lodges were occupied by winter hunting parties from various Middle Missouri villages. Some conical lodges were built or used by villagers escaping the ravages of eighteenth and nineteenth-century smallpox epidemics. Further west, across the broad arc of the Northwestern Plains and the Wyoming Basin, conical shelters were constructed, used, and reused as war lodges throughout Protohistoric and Historic periods, and perhaps earlier, by many Plains Indian groups. These structures were scattered throughout mountain ranges, foothills, and river bottoms in secluded but relatively accessible areas for staging raids and conducting warfare among enemy tribes. Lodges were built of sturdy timber to maintain warmth in winter, concealment, and protection from enemy attacks. As warfare intensified in the Historic period, Plains Indian groups expanded their use of cribbed timber structures, forts, defensive breastworks, entrenchments, and also built fences and horse corrals. At the same time, conical lodges throughout this region functioned as temporary hunting camps and emergency shelters. Simple pole and brush structures served various special purposes as cooking and hide preparation areas, menstrual huts, elopement lodges, ceremonial spaces, storm shelters, and caches. Band members who could not attain sufficient hides for tipis resorted to pole and brush structures for shelter. On the western periphery of the Northwestern Plains in the Central Rocky Mountains, some conical lodges functioned as domestic residences. Among Shoshone bands, an ancient tradition of willow, brush, and grass domiciles (wickiups) in the Great Basin apparently translated into more sturdy, durable timber housing (conical timber lodges) in the central Rockies and Northwestern Plains during the Protohistoric and Historic Periods, if not significantly earlier. The origin and cultural associations of conical lodges remain problematic given the entangled culture history of the Central Rocky Mountains and Northwestern Plains during the Protohistoric and Historic periods. Archaeological evidence from a few conical lodge sites in southwest Montana and northwest Wyoming indicates Shoshone and possibly Crow habitation. In addition, ethnographic evidence strongly points to the Arikara, Mandan and other groups as the builders of conical lodges along the Little Missouri River. Otherwise, for the majority of reported conical lodges, cultural association is unknown. Understanding the origin, age, use, and cultural association of conical timber lodges ultimately requires immediate and more rigorous investigation and standardized recording of the surviving conical pole structures. Research must be contextualized with ethnohistorical data and by tribal-descendant community collaboration and input. These baseline data may eventually enable researchers to more fully incorporate conical timber lodges and other perishable wood structures into broader research contexts, including Protohistoric and Historic period hunter–gatherer social structure, seasonality, mobility, trade, adaptations, militarism, colonialism, and culture change on the Northwestern Plains and Central Rocky Mountains. Accurate lodge information is also essential to informed CRM practice on public lands, particularly wildfire protection and vandalism prevention. Conical timber lodge investigation is a race against time as natural deterioration, wildfire, livestock grazing, and vandalism threaten this highly fragile and rapidly vanishing archaeological resource.
