consisted of eight 5-foot squares. Hach square was given a designa- 
tion according to its location on a grid oriented on magnetic north. 
The method of excavation was the same as applied to the test pits. 
Square North 300 West 25, located at the east end of the trench, was 
excavated to 48 inches below the surface in order to investigate the 
possibility of a deep or unknown occupation level. Approximately 
10 inches from the bottom, the soil profile revealed long, thin lenses 
of light-colored silt. These lenses appeared to have been caused by 
deposition in times of flooding. All the other squares were scraped 
down through the 18-inch level. Not a single artifact was located 
below the plow zone, but within it a scanty concentration of cultural 
material was encountered. During the preliminary investigation of 
Excavation Unit 1, some small, dark, circular soil stains were noticed. 
At first these stains were thought to be rodent runs, but after cross 
sectioning and coring out each of them, they were definitely estab- 
lished as being postmolds. Soil within each of the molds was darker 
in color and less compact than the surrounding earth. The postmolds 
seemed to show a denser distribution toward the south side of the 
trench, so the entire excavation was extended an additional 15 feet 
to the south. By scraping the soil, a total of 162 postmolds were lo- 
cated in an area 20 by 40 feet. A few of the postmolds contained bits 
of charcoal; one contained a potsherd, and another a few kernels of 
corn. The majority of the stains were encountered between 9 and 12 
inches below the surface. Their diameters ranged from 1 to 6 inches, 
with the majority measuring from 2 to 3 inches. The depth of the 
actual postmolds ranged from 0.5 to 7.5 inches, but most of them were 
from 2 to 4 inches deep. Their distribution appeared as a random 
scattering and lacked any indication as to the type or number of the 
structures they represented (pl. 47, a). 
Owing to the short time available, and with other sites yet to be 
investigated, it was decided to hire a bulldozer in order to see what 
would be encountered if a large area of the subsoil was revealed. 
A Cat-8 was employed to remove a small amount of the topsoil. <A 
north-south trench and an east-west trench were 10 feet wide and 
together 232.5 feet long. Twelve inches of the topsoil was removed. 
The crew followed the bulldozer, marking anything that appeared 
archeologically significant (pl. 47, 5). The dirt piles on the sides 
of the trenches were also investigated. Within the trench cuts, only 
two cultural features were located. Feature 41 in the north-south 
trench revealed what appeared to be a charred cornstalk and some 
burned earth about 5.6 inches beneath the surface. ‘Two postholes, 
lying about 2 inches apart, were located 6 feet west of the burned 
area. One had a diameter of 2 inches and a depth of 8 inches; the 
other measured 1.5 inches in diameter and 3.5 inches in depth. A
