POLLEN ANALYSIS OF SAMPLES FROM THE DEPRESSION SITE (48SW13490), BLACK BUTTES PROJECT, SOUTHWESTERN WYOMING

Author(s): Linda Scott Cummings; R.A. Varney

Year: 2003

Summary

The Depression Site (48SW13490) is located southeast of Point of Rocks at the eastern

edge of the Rock Springs Uplift in Sweetwater County, southwestern Wyoming. Rose Springs

points recovered from the Trench 7 block indicate a Late Prehistoric occupation. The Trench 8

block yielded evidence of two occupations, an Upper component, which is attributed to Rose

Springs people of the Late Prehistoric, and a Lower component that appears to represent an

Archaic occupation. Calibrated radiocarbon ages for the Late Prehistoric occupation are 1260-

960 BP and 970-750 BP for Features 14 and 6, respectively. The Archaic occupation is

anchored by a calibrated radiocarbon age of 5660-5470 BP (Feature 15) (Darlington, personal

communication, January 3, 2003). Pollen analysis was conducted on samples from seven

features to examine evidence of vegetation and possibly human activity during both the Archaic

and Rose Springs occupations at this site. In addition, four samples were examined from

possible occupation surfaces around Feature 16.
