Results and Discussion
The two levels represented in the section from M11 extend over the whole area of excavation and make up most of the deposits of the site. A late Pleistocene bouldery gravel, with which is included some variegated silty and clayey alluvium, is separated from the overlying dark-colored sandy and silty “alluvium” by a definite erosional break representing an unknown interval of time (Hunt, this report). There is a higher red sand layer and a younger bed of dusty brown fill which is found just below the surface; both of these are relatively quite thin and extend only over part of the area of the site. As the dark-colored homogeneous sands and silts made up most of the deposits of the site, and contained most of the cultural remains, they will be our particular concern.
The results of sieve analyses made on the samples from the front and back of the site have been summarized in Tables VIa and VIb; the breakdown into the various particle size fractions is by weight. This was done to 1) describe the physical nature of the deposits and 2) to determine the nature of textural variation of the samples.
