size. One of the hearths, Feature 3, was rock-filled, while the other 
two, Features 8 and 9, were represented by circular fire-burned out- 
lines containing ash, flecks of charcoal, and charred and unburned 
bone fragments (pl. 38, a). 
The bone layer consisted of scattered whole and broken bones, like 
those already noted, which rested directly upon a compact dark gray- 
ish-colored clay layer 8 feet beneath the present surface. Most of the 
bones were either sections of ribs, fractured or cracked long bones, 
whole foot bones, or an occasional lumbar vertebra, all belonging to 
the bison group (pl. 89, a). Bones of dog (Canis familiaris), wolf 
(Canis lupus), deer (Odocoileus sp.), and occasional bones of elk 
(Cervus canadensis), antelope (Antilocapra americana), and jack- 
rabbit (Lepus townsendii)? were present, but never in any quan- 
tity (pl. 40, 0). 
Section 7.—The final section was located 68 feet south of Section 
6 and was the largest section to be excavated. It measured 25 feet 
in length, 6 feet or over in width, and at the close of the excavation 
was slightly over 10 feet in depth. 
top a dark-gray clay stratum 5.6 feet from the present surface 
and in the southwest corner of the section, a quarter portion of an 
ash-filled hearth, Feature 1, was uncovered. Nothing was found 
adjacent to or upon the same level as the hearth (pl. 38, 0). 
The first concentration of cultural deposit, Feature 20, occurred at 
the 8-foot level. This consisted of articulated and disarticulated 
sections of bison (Bison bison bison), deer, antelope, elk, and jack- 
rabbit as well as portions of dog and wolf (pl. 40, a, 41, 6). A skull 
of a bison cow had a hole knocked into the brain cavity for the ex- 
traction of the brains (pl. 41,a@). In association with these bones were 
a number of fire-cracked and/or broken river cobbles as well as a few 
potsherds and chips of obsidian and chalcedony besides a few bone 
and stone artifacts. Most of the bones were in their natural state, 
although some had been broken so as to extract the marrow content. 
SPECIMENS 
In the laboratory some of the sherds were combined into larger 
sections (pl. 42). As Cooper (1955, p. 27) and Wedel (1951, p. 181) 
have mentioned, these sherds are of a compact black-colored paste 
whose exterior surfaces varied in color from a light gray to tan to a 
dull black with fire clouds rather dominant. Tempering material, visi- 
ble on the broken edges, appears to be mostly a natural sand with only 
a rare bit of crushed granite showing. Upon the exterior and interior 
surfaces of some of the sherds there appears a heavy carbonized layer
