of the Santa Fe River. These unconsolidated to poorly consolidated sediments are locally derived (shed from
the foothills and the Sangre de Cristo Mountains), and are of alluvial origin (predominately fan material). The
Ancha formation is generally more than 10 m thick, and has a gentle south-westward dip of ~5°. Contacts with
underlying units are generally poorly exposed, but typically form a distinct angular unconformity with the more
steeply dipping Tesuque formation. The Ancha Formation is generally a beige-colored unit that becomes lighter
in color near the upper surface from calcium carbonate-rich soils. The underlying Tesuque Formation is reddish
which helps to distinguish it from the lithologically similar Ancha Formation. The Ancha formation contains Qbt
in upper 1-2 meters in places along Arroyo Hondo which places a minimum age of 1.66 ± 0.030 Ma on most of
the unit and an approximate age for the formation of the Ancha constructional before net incision of the region
occurred in the early Pleistocene. Aggradation appears to have continued into the middle to late Pleistocene in
some canyons along the mountain front (Koning, Connell, Pazzaglia, and McIntosh, 2002).

Granodiorite to Diorite (Paleoproterozoic?) – Generally medium-grained dark, weakly foliated-to-unfoliated

A geologic map displays information on the distribution, nature, orientation, and age relationships of
rock and deposits and the occurrence of structural features. Geologic and fault contacts are irregular
surfaces that form boundaries between different types or ages of units. Data depicted on this geologic
unpublished work, and photogeologic interpretation. Locations of contacts are not surveyed, but are
plotted by interpretation of the position of a given contact onto a topographic base map; therefore, the
accuracy of contact locations depends on the scale of mapping and the interpretation of the geologist(s).
Any enlargement of this map could cause misunderstanding in the detail of mapping and may result in
