Pre-Columbian Archaeology
of North America
Regional Chronologies:
Week 8 – the Southwest
General Characteristics
Three major ecozones and culture regions:
–
–
–
–
Key factors are rainfall, temperature, number of frost free days, farmland availability, water
sources, floodwater.
Plant categories: wild and domesticated. Domesticated plants appear in the SW by 3500 BP.
Domesticated are genetically altered and dependent, to some extent, on human propagation.
Cultivated are the same genetically as wild, tough planted and cared for by humans.
•
•
Hohokam Region: Sonoran Desert
–
advantage- lush desert with wild food plants year around:
•
•
•
•
•
•
•
spring wild barley, agave (Yucca mohavensis), cholla (Opuntia sp.) buds
summer saguaro (Carnegiea gigantea) fruits
fall and winter mesquite (Prosopis juliflora), acorns, prickly pear (Opuntia).
Cultigens are agave.
Farming of corn, various beans, squash, gourds, supported by large-scale irrigation on flood plains.
Fauna of rabbits and fish, small game.
Mogollon Region:
–
–
–
–
Mountainous regions (max. elevation 3500 m)
Forests rich in plants but not in human foods
Diverse wild resources are cacti, mesquite, piñon (e.g. Pinus ediuls), mesquite, acorns, but
not abundant.
Farming of small patches of arable land by rainfall and floodwater farming.
•
•
Agave.
Mimbres used floodplain irrigation. Weather often not ideal, wet and cool or warm and dry. Population
smaller than Pueblo or Hohokam areas.

Southwest (1)
Archaic Period
– 8,000 - 1,800 BP.
• Altitherm was 7,000 - 4,500 BP.
– More regionalism of cultures with diverse projectile point traditions, side-notched,
corner-notched, and barbed points, evidence varying hunting strategies.
– Broad spectrum adaptation to small game and plant resources, especially rabbits
and seeds.
– Technology includes digging sticks, serrated stone, ground stones, manos and
metates, storage baskets.
– Yields fruit 3k - 9k cal/hr, nuts 1k - 2k cal/hr, seeds 200 - 600 cal/hr.
– Tome and space scheduling requires intense knowledge of landscape.
– Residential and logistical mobility.

Tornillo 3225 BP, Mogollon Desert in SW NM
Bat Cave 3441 BP, West NM
Three Fir Shelter 3040 BP, Colorado Plateau
Milagro 2780 BP, Sonoran Desert near Tucson associated with pithouses.
Early domesticates spread quickly.
– Late Archaic (1500 - 200 BC) had corn, gourds and squash, associated with
pithouses.
• Earliest sedentary farmers are in the Sonoran Desert.
• Slow change to sedentism is attributed to cultural evolution and genetic evolution.
•
Later development divided into three distinct culture regions
– Anasazi
– Mogollon/Mimbres
– Hohokam
Southwest (2)
•
Basketmaker II
– 2200 - 1500 BP
– Most models that attempt to explain the cultural innovations of BMII assume in situ
adoption of agriculture by late Archaic populations.
– Many lines of evidence show BMII dependence on corn agriculture:
• Burned and unburned corn recovered from trash middens, storage pits, burials
• Corn found in dessicated human feces (coprolites)
• Locations of BMII sites (unlike Archaic sites) often in areas of good, deep soils or near
washes where cultivation could have taken place
• Carbon isotope ratios of BMII human bones are different from these ratios in the bones of
Archaic populations, in a way that indicates a BMII diet rich in corn.
– Pithouses associated with residential seasonal mobility, multi-year use.
• Wide variability, including large, deep forms and shallow, basin-shaped forms.
• Foundations are made of a wide variety of materials, cribbed logs and rock. Walls are not
often preserved, but these were made of poles and brush, jacal, and stacked logs.
• BMII pithouses are circular to oval in shape, with entryways facing to the south or east.
Firepits are often in the center of the house.
• Some houses were placed in rock shelters, but most were constructed out in the open.
– Subterranean storage cists (for corn, piñon nuts, and other foods), often lined with
slabs, but sometimes simply dug below the ground in the shape of a jug or bell.
– Generally speaking, no ceramics
– Atlatl and throwing spear (dart), no bow-and-arrow. (The atlatl/throwing spear
combination was also found in the Archaic, in BMIII, and in later Pueblo times, but in
BMII it was the main form of weapon/hunting tool).
– Multi-year middens, more burials than during Archaic
•
Southwest (3)
Basketmaker III
– 1500 - 1200 BP
– BMIII is a continuation and elaboration of the BMII adaptation. During BMIII, there
appear a number of cultural innovations, but many of the ways of BMII also
continue.
• There is good evidence that population has increased by BMIII, and that villages have
become larger. There are many more BMIII sites than BMII sites, and they are spread over
a wider area.
• At some BMIII sites, one or a few exceptionally large pit structures are found. These are
interpreted as some form of communal gathering place, perhaps the earliest expression of a
great kiva.
• These structures suggest that BMIII societies were socially integrated at a level not seen in
BMII, i.e., there was some form of intra- or even inter-village cooperation regarding
important decisions and ceremonies.
– Beans and pottery
• Beans (lysine) = complete protein. Pottery used to cook beans = maximized caloric return.
• Pottery = less mobility
– Turkeys being raised for meat and feathers
– Bow and arrow, smaller points indicate new adaptations.
– More storage pits and cists
– Pithouses more substantial and “great kivas” appear.
• Many BMIII pithouses have large alcoves or vestibules; raised ridges in the floor dividing the
house into sections; slabs lining the walls of the pithouse; and a large hearth in the center of
the pithouse.
Southwest (4)
• Comparing BMIII sites:
– Shabik’eshchee had a communal economy
• Dendrochronology: construction begins c. 1450 BP, continuing
to c. 1200 BP
• 70 small, standardized pit houses with small antechambers
suitable for two persons
• 47 cists, few storage pits in houses
• large subterranean circular structure “great kiva”
• storage and caching visible to community
• burials outside pithouses.
• Maximum population may have been as high as 77 people (avg.
for BMIII is 15)
– The SU site had a household based economy:
•
•
•
•
35 large, variably sized, larger antechambered pit houses
one large pithouse
storage inside homes and less visible
diverse burials.
Southwest (5)
•
Pueblo I (PI-III: Anasazi)
– 1300 - 1100 BP
– The transition from BMIII to PI is not abrupt, nor does it involve an influx of new
people
– Changes from BMIII to PI are thus gradual and evolutionary, though when we
compare overall trends from the two time periods, many differences can be seen.
– Cranial deformation associated with the introduction of a new type of cradle board
– Year round occupation in pueblos with above ground rooms, some pit houses, pit
structures have some ritual features
• Typical site a double row of rooms fronted by pit structures
– Winter use of pits. Structures are warm and cold adapted.
– Living rooms have storage rooms attached.
• Toward the end of PI, the above-ground architectural form shifts from insubstantial jacal
structures to rectangular masonry rooms. These are often arranged end-to-end in "blocks"
of rooms. There is evidence (hearths and other floor features, as well as artifacts found on
the floors) that such room blocks were used for a combination of habitation, storage, and
special activities such as food preparation and manufacture of crafts.
–
–
–
–
Household based economies and less sharing.
Field houses indicate claim to land areas.
Plant remains support continuous, year round occupation.
First corrugated and black-on-white pottery appears (probably by about 1200 BP),
along with black-on-red styles
• There is evolution of designs from the crude an sparse designs of BMIII pottery (which often
resemble the designs woven into BMIII baskets), to more elaborate and widely distributed
styles of painted decoration which do not match basketry designs
– clearly pottery has emerged by PI as an important medium for new symbolic expressions
• The corrugated pottery usually consists of thick corrugations confined to the neck of the pot.
•
Southwest (6)
In a few places, large villages arise during PI, which exceed the size of the largest BMIII villages and
reflect different and probably more complex forms of social organization.
–

–
•
McPhee village
–
–
–
–
•
–
•
The dendroclimatic evidence (evidence of yearly rainfall values based on tree rings) did not indicate that such
aggregations took place during years that might have produced agricultural surplus.
Instead, it appears that aggregations took place during times when there were no severe droughts that would
have forced people to disperse and move to more favorable agricultural locations.
The abandonment of these PI villages does seem to have been correlated with periods of drought,
implying that the social organizations that were formed during the good times (agriculturally speaking)
were relatively fragile, and the social bonds were relatively easily broken.
As with the BMIII villages, there is no good evidence for "elite" leaders with substantial political power
–
•
40 households (120+ people) lived there at the peak of occupation
Evidence of other, larger villages in the area
Because of the limited amount of non-agricultural food resources in these areas, some have proposed
that large villages formed during climatic conditions that fostered consecutive years of adequate
agricultural production.
–
•
21 room blocks and a remote kiva.
1200 BP: 2 great kivas 22.5 m in diameter.
1160-1100 BP: oversized pit structures - 5 m - central in room blocks with elaborate sipapus and footdrums.
Circa 1100 BP: abandonment with pit structures burned, burying bodies in the floor.
Grand Mesa Village
–
–
•
Many of these villages involve multiple units of linear, arc-shaped, or U-shaped rows of masonry rooms, with
doorways facing an open area containing one or more kivas.
In the larger villages, there are one or a few exceptionally large, circular structures that can be considered as
great kivas.
In some cases, it appears that these great kivas did not have roofs, and were large, open-air gathering places.
Again, in spite of the fact that there were intra- or inter-village ceremonial organizations (reflected in the great
kivas), the religious and political power may have been dispersed among a number of individuals and
households, and social organization was relatively egalitarian.
There is much evidence that the room blocks surrounding the kivas were used for "potluck" feasting,
wherein large quantities of food were prepared and eaten on a periodic basis.
–
This evidence may indicate something about periodic ceremonial events involving large numbers of people
congregating at the great kivas.

Further elaboration of black-on-white, black-on-red, and gray ware pottery.
Toward the end of PII, the first “polychrome” ceramics appear, painted in red, orange, and black designs.
Black-on-white ceramic styles are very widespread and generally similar across vast areas, with some minor
local variation.
During PII, there is evolution of the gray ware “corrugated” pottery. Early in PII, the common form of corrugation
is neck banding, similar to the style of PI. However, through time the neck bands become smaller and more
elaborate, with the corrugations often finely pinched with the fingers to make small, scalloped designs.
In middle to late PII, the pottery becomes corrugated all over, sometimes with very deeply and finely pinched
corrugations.
After the mid-1000s, many of the black-on-white and black-on-red pottery styles across a broad area of the
northern Southwest show some influence from designs originating from Chaco Canyon.

Organization.

•
Chaco Canyon is seen as a center for the regional system.
The number of storage rooms may have been for redistribution purposes.
The sites with outlier great houses are seen as part of the regional system. These populations
utilized the canyon sites for gatherings.
The center may also have served as a trade center. Roads often connected the sites.
The region was tied together around Chaco Canyon. With Chaco Canyon acting as a ritual
center and trade center.
The low number of residents in Chaco Canyon would indicate that the visitors to the canyon
came from the outliers.
Social organization during PII is not well understood particularly with respect to the
Chaco system.
–
–
–
–
–
Was Chaco a mighty empire with the ability to coerce and control outlying populations, or was it a
great religious and ceremonial system that was a place of pilgrimage?
The debate has convincing arguments on both sides.
David Wilcox has argued in various publications that the Chacoans were able to send out
relatively small but well-trained and fearsome groups of armed men to control outlying
populations and demand "tribute" (gifts of food and other valuable items) for consumption or use
by elites living in the Canyon Great Houses and in the outlying Great Houses.
Others (Steve Lekson, John Stein) have argued that Chaco may have been a great
ceremonial/religious center, where pilgrims came to participate in feasting and ceremonies. It is
interesting to note that some of the features of Chaco Canyon (arc-shaped room blocks, great
kivas, evidence for mass consumption of food) were also present in PI sites (see above).
Was the Chaco system then the driving intellectual, philosophical, and religious force of the 900s
through early 1100s, or did it merely reflect and reinforce ancient concepts and principles of the
Anasazi?

Mesa Verde had largest aggregation in SW after 1150.
There is continued elaboration of ceramic production, with regional ceramic design styles arising that are
quite distinctive.
In many areas, it is clear that there is ceramic specialization, with a few artisans producing pots for export.
There is a tendency for the gray corrugated pottery to decline in quality, but other forms, especially the
black-on-white types, achieve their finest expression.
Toward the end of the PIII period, there appear polychrome pots pained in orange, red, black, and white.
These form the basis for many of the later PIV polychrome pottery traditions.

•
Pottery Classic; 1000-1150, elaborate black on white, naturalistic and abstract pattern, homogeneous style with
apparent rules of painting. Iconographic conventions include many rabbits, sheep, copulation, unusual animals,
humans, masks, mesoamerican themes and plumed serpents.
Postclassic; 1150 -1250, Classic Mimbres pots in use in Postclassic. Mimbres iconography discontinued. New
technology added to plainware. A diverse variety of pottery types associated with different areas of the Southwest
at Postclassic hamlets. Classic Mimbres iconography is continued after 1150. Reserve-Tularosa technological
style imported.
Interpretation of the evidence: Ideology of conformity during the Classic.
New technology indicates influx of some new people.
Regional interaction increased post 1150 with greater social interaction and movement of people.

•
Agricultural practices
–
–
•
Mimbres Classic period was marked by aggregated villages with several hundred inhabitants.
Postclassic saw population disbursement to small hamlets.
A breakdown in social structure, and land degradation could be reasons for abandonment of Classic villages.
Classic period pottery has distinct and ubiquitous iconography.
–
–
•
Classic; irrigation systems were in use, water control features, bordered fields with ditched and terraces, low tech
and labor intensive, intense farming of corn and beans.
Postclassic; All hearths had cultigens, change from large scale irrigation systems to dispersed. Interpretation of
the evidence: There was a degradation of the environment from long and continuous use. Cultigen evidence
indicates same manner of subsistence, with change in areas farmed.
General interpretation: Mimbres classical abandonment was actually a reorganization. Community
and regional relations were redefined at a broader and less restrictive level.
–
–
–
•
Classic; clustering of rooms indicates gradual expansion of population. no evidence of hierarchy, residential stability, residential
stability was a non-sustainable subsistence pattern.
Postclassic; remodeling of field houses indicates continuity, Flat radiocarbon date indicate continuity.
Iconography does not appear in Postclassic contexts.
Therefore, social control/organization does not appear to exist, or weakens considerably, after 1150.
There is a high ubiquity of cultigens in Mimbres Classic period hearths. There are cultigens found in
100% of all Post-classic hearths studied
–
Therefore, it would seem that Postclassic Mimbres are still cultivating at least as much as the Classic Mimbres.

Discussion: Ways in which the focus, or scale of observation, affect our understanding of prehistoric
‘abandonmenst’ with reference to the Mimbres and Mesa Verde ‘abandonments.’
Focusing only on a small area may give the impression that a region has been abandoned. The
Mimbres valley may have been abandoned, but the Mimbres region evidences continuity of
occupation.
In this case a regional view is adequate to assess what really occurred.
In the case of the Mesa Verde abandonment a much wider view is needed. The Mesa Verde
populations did abandon the region and moved to the Rio Grande Valley, a movement of greater
distance than the Mimbres.
The Mesa Verde movement can be called an abandonment, the Mimbres is best viewed as a regional
reorganization. A camera viewfinder is an excellent analogy because a number of push and pull
factors may lead a population away from an area that they had historically occupied. In the camera
example, a narrow focus of the camera would indicate that the area was abandoned and the
inhabitants disappeared, when in fact they had just moved out of the view of the camera. In the case
of the Mimbres, the population did not abandon the region, signaling the end of the Mimbres culture.
Rather they disbursed to smaller hamlets to the east. If we do not expand our scale of observation it
would be easy to assume that they had disappeared. The scale of observation needs to be larger for
the Mesa Verde region. Its inhabitants moved all the way to the Rio Grande Valley 200 miles distant.
The following commentary on this document regarding the Mimbres material was provided by Dr.
Harry J. Shafer of the Department of Anthropology at Texas A&M University:
–
–
–
Mimbre architecture: There are at least six different functional types of rooms, and the occurrence of these
functional types depends on the size of the social group, and whether it is an extended family or corporate
group. Features in rooms and the way they articulate with other rooms defines the room type. There is a great
deal of variability in the use of building materials, depending on the location relative to the kind of available stone,
and when the room was constructed. Great kivas during the pithouse-pueblo transition (A.D. 900-1000) had
sipapus, and Classic corporate kivas had rectangular floor vaults placed next to the hearth.
Mimbres mortuary practices: Intramural burials, which account for 85% of all Classic period burials, were lineage
cemteries placed beneath certain types of rooms. Extramural burials included inhumations (10%) and
cremations (5%).
Mimbres pottery: Style III painted pottery ceased to be produced probably before A.D.1150. Arguments for
continued use after 1150, are based on radiocarbon dates. A microstylistic sequence worked out for Style III
based on tree-ring dates indicates the rules of design began to break down after A.D. 1100. Style II and III were
but one of a number of material correlates that relate to the organization of Mimbres society involved in irrigation
agriculture. When the system broke down after A.D. 1130, the pottery ceased to be made but heirloom vessels
may have been used up to mid century.

Adobe compounds replace pit houses during Classic.
Hohokam redware changes from Gila Red (to 1300) to Salt Red evidencing change in exchange.
During the Classic platform mounds replace ballcourts and are concentrated.

Mounds are built of solid fill with stone or adobe exterior retaining walls
Mounds had rooms built on them after 1250
Mounds had courtyards and enclosure walls. These may have served to limit access.
Similarities: Both ballcourts and platform mounds were ceremonial in nature, both were constructed as public
works; both mounds and ballcourts acted as unifying elements within the culture; both probably facilitated trade.
Exchange and interaction is similar and continued from the pre-classic to the classic period
Differences: Residences were built on platform mounds; ballcourts were built throughout Hohokam regional
system, while platform mounds were concentrated in Phoenix, Salt River, Gila River and southern Arizona.
Ballcourts were accessible to everyone, but the mounds were occupied by only a few individuals. Mounds more
labor intensive to construct
Mounds seemed to service village clusters, while ballcourts were distributed in most villages. Ballcourts were
phased out and platform mounds became more prevalent. Society moving toward greater complexity.

Interpretation: The mounds and ballcourts are interpreted as indicating a shared cosmology and ritual pattern.
Different communities gathered together at ballcourts and at platform mounds, with more centralization at the
later. The scale of social, political and ritual organization shifted to larger units with a hierarchy. The society
evolved from simple to more complex. The mounds and ballcourts were constructed as public works; both
mounds and ballcourts acted as unifying elements within the culture; both probably facilitated trade;

Pit house
•
•
Almost all of these pithouses
consisted of a large living room
and a smaller antechamber.
Using stone and wooden tools,
the people dug a rounded or
oblong-shaped depression
several feet into the ground.
Usually there was a low bench
surrounding the floor area with
four timbers placed in holes in
each corner to support a roof
framework. Timbers were
placed across the tops of the
four posts with smaller logs,
sticks, juniper bark, and mud to
cover the framework to make it
weatherproof.
The larger room, used as
sleeping quarters and a general
work area, was divided into two
sections by a low wall
extending toward the firepit.
Utensils and other implements
for food preparation are often
found behind this low wall, and
the antechamber was probably
a large storage area. Entrance
to the pithouse was by means
of a ladder through an opening
in the roof above the centrally
located firepit.

Pueblo Bonito is the largest
ancient dwelling at Chaco
Canyon, and in fact the
largest known Anasazi
dwelling.
The South wall (running
vertically along the right of
the photograph) is nearly 175
meters long.
Pueblo Bonito grew through
four major construction
phases, starting in the early
tenth century with a
semicircular row of rooms
(coinciding roughly with the
left curved outer portion of
the building), culminating in
1120 with over 650 rooms
and an estimated resident
population of 400-1000.

Reconstruction
Located about 3500 feet
north of Pueblo Bonito,
Pueblo Alto is the highest
village at Chaco Canyon,
and may have been a
place of communication
into what is now Mexico
via fire signals. There is
one possible tower kiva,
but otherwise the entire
village is single storey
construction.
The village's 110 rooms
and eleven kivas were
constructed between 1020
AD and 1140 AD. It was
abandoned ten years later.
Seven prehistoric roads
radiated outwards from
Pueblo Alto. It is a place
were turquoise was
processed for ritual
objects. The source of the
turquoise used here was
near present-day Cerillos,
south of Santa Fe.

Mogollon: Early Pit House architecture
• Early Mimbres architecture
consisted of subterranean
pithouses.
• The walls of these
structures were made of
soil, upon which plaster was
applied.
• The pithouse was entered
through the roof, then later
by an inclined entrance
from the surface.
• Later pithouses were
constructed of rubble
masonry and were semisubterranean.
Mogollon: Early Pit House Ceramics
• The San Francisco Red
pottery type is
characterized by a deep
red slip applied to the
interiors of bowls and the
exteriors of jars.
• This pottery is highly
polished and has an
extremely smooth
surface.
• The red slip is made
from hematite added to a
clay suspension in water.
Mogollon: Late Pit House architecture
•
During the Late Pithouse period two
distinct phases of pithouse
architecture can be determined.
– From AD 550 to 650 (Georgetown
Phase) pithouses were round with
simple hearths and no internal
divisions. Large wooden posts
supported the roofs. The structures
were systematically cleaned out
before they were abandoned.
– From AD 900 to 1000 (Late Three
Circle Phase) pithouses changed
from circular to rectangular in shape
and the walls were constructed of
masonry one meter above the
ground surface. Hearths became
more elaborate and also became
rectangular rather than circular, and
small holes constructed in the roof
allowed smoke from the hearth to
escape. These pithouses were
burned before they were
abandoned.
– Pueblo room blocks appeared after
AD 1000 as a response to the
increase in population and
agricultural intensification in the
Mimbres Valley.
Mogollon: Late Pit House Ceramics (1)
•
•
Black-on-white style I, or Boldface
Black-on-white, pottery type was made
from AD 750 until AD 900. It is
characterized by a thin, chalky, white slip
applied to the interiors of bowls and the
exteriors of jars. The paint is black
although sometimes it is red due to
misfiring. The painted designs extend to
the rim and are executed in thick lines.
The designs consist of large scrolls,
wavy-line hatchure, a three-pronged F,
and rare, crude naturalistic designs.
The Black-on-white style II, or
Transitional Black-on-white, pottery type
was made from AD 900 until AD 1020. It
is characterized by a thin, chalky, white
slip applied to the interiors of bowls and
the exteriors of jars. Early designs
extended to the rim but later designs
stop short of the rim when rim bands
develop. The designs were more
complex and there were varied motifs.
Designs included linear and curvilinear
designs, straight-line hatchuring
bounded by thick bordering lines, thickline interlocking scrolls, and some
naturalistic designs.
Mogollon: Late Pit House Ceramics (2)
• The Black-on-white style
II/III pottery type was
made from AD 970 until
AD 1020. This style
bridges the Black-onwhite styles II and III. It is
characterized by the
development of the use of
multiple, fine framing
lines, finer linework, and
more careful execution of
the designs. Geometric
and figurative images
were begun to be painted
in negative form.
Mogollon: Classic/Post-Classic architecture
•
•
The Classic Mimbres period dates
from AD 1000 to 1140. Masonrywalled pueblos were built over Late
Pithouse period pithouses. These
pueblos consisted of living rooms,
storage rooms, and civicceremonial rooms. There was a
major increase in the population
due to irrigation agriculture and
more intensive and extensive
exploitation of the environment.
The Postclassic Mimbres period
dates from AD 1140 to 1450 and is
divided into two phases. The Black
Mountain Phase dates from AD
1140 to 1300. During this phase the
population moved towards the
south. There was no building of
ceremonial architecture (kivas) and
the pottery was either local
utilitarian or non-local painted ware.
The Cliff Phase dates from AD 1300
to 1450 and is characterized by
adobe architecture

The Black-on-white style III, or
Classic Mimbres Black-onwhite, pottery type was made
from AD 1010 until AD 1130. It
is characterized by a thin,
chalky, white slip applied to the
interiors of bowls and the
exteriors of jars. Framing line
bands, or rim bands, were
almost universal and often
multiple bands present.
Geometric and naturalistic
designs were painted on the
pottery. Designs included thin
line hatchure bordered by thin
lines, and wide and narrow
concentric bands
The Polychrome style III
pottery type was similar to
Black-on-white style III with the
exception of the use of a third
color, ranging from tan to
yellow, in place of fine-line
hatchure or as filler in a
naturalistic element.
Hohokam: Ballcourts
Hohokam: Pueblo Grande Mound
•
The platform mound at Pueblo Grande is one of the largest the Hohokam ever constructed. Like
the northwest ballcourt, it is oriented in a general north-south direction and measures 49 by 90
m, approximately the size of a modern-day football field. At its greatest height, the mound stood
7.5 to 9 m high. Surrounding the entire mound, a 2 m high and 1 m wide (1 m) compound wall
restricted access to all but a selected group of individuals.
Hohokam Ceramics
• The Hohokam adopted
stylistic elements of
Mesoamerican origin
and their settlement
patterns resemble those
of the adjacent Mexican
states Sonora and
Sinaloa more than the
Puebloan north.
Southern influences
include ceramic styles,
figurines, censers, and
palettes.
