those of the upper and lower deposits. These two sherds, after being 
allowed to dry thoroughly, regained much of their original hardness 
and showed that their exterior surfaces had been treated with a cord- 
wrapped paddle. Their shape indicated the basal portions of a co- 
noidal jar. These features are diagnostic of an Early Woodland 
pottery. Fire clouds are much in evidence, and the paste is highly 
contorted, having a tendency to flake easily. It was tempered with 
natural sands, mostly quartzites, and fired under a reduced atmosphere, 
giving it a dull gray color. 
Interspersed in the superstrata were numerous small fragments of 
Bison bones, none of which were burned or showed convincing 
evidence of intentional modification into artifacts. No other cultural 
features were found in this section. 
Section 2—Twenty-eight feet beyond and south of Section 1, a 
second section was excavated. It measured 22 feet in length, slightly 
over 5 feet in width, and 7 feet in depth (fig. 39, Section 2). Scattered 
through the deposits were a number of Sison bones as well as some 
stone material. 
At a depth of 1.6 feet below the surface was a concentration of very 
small flint and obsidian chips, Feature 16. They were incorporated 
in the same gray clay stratum from which the sherds were obtained 
in Section 1. The stratum at this point had increased in thickness to 
0.4 foot. After all the overlying strata were removed, without finding 
anything of significance, it was noted that these chips were in direct 
association with a number of crude scrapers which had either been 
intentionally discarded or lost during the period of manufacture and 
occupancy. None of these artifacts was diagnostic enough to indicate 
any particular cultural group, but since they lay within the same 
stratum as the sherds, we have assumed that all belonged to the same 
time period as the Early Woodland culture. 
At a depth of 2.5 feet from the present surface, in the southeast 
corner of Section 2, a hearth area 2.8 feet in maximum length and 2.2 
feet in maximum width was uncovered (Feature 7). It was flat 
across the top, of a brick-red color due to action of heat, and was 
covered with a thin layer of whitish wood ash in which there were bits 
of charcoal and sections of partially charred wood. As much of the 
charcoal and charred material as possible was saved for carbon-14 
tests to determine, if possible, the age of the deposit. (At the present 
writing these tests have not been made.) We could not identify any 
prepared floor or living platform surrounding the hearth, and no 
artifacts were in the deposits above, below, or in its immediate vicinity. 
At the 4.8-foot level, which was a continuation of the lowest dark 
gray (Woodland) stratum, part of another hearth, Feature 5, was
