POLLEN ANALYSIS OF A STRATIGRAPHIC PROFILE AND A FEATURE AT 48SW13156, SWEETWATER COUNTY, WYOMING

Summary

Site 48SW13156 is a buried, open camp site, containing numerous features and stains

dating to between 9430±40 and 8150±40 RCYBP. All of the features were noted in the lower

portion of stratum A or the upper portion of stratum E. Two modern samples, collected from

different modern vegetation communities, were analyzed as controls for the site. Eleven

stratigraphic samples collected at ten centimeter intervals from a buried A horizon that overlaid

the cultural A stratum 90wn through stratum K were analyzed to assess changes in the

vegetative community in the area and to evaluate the potential for plant use by occupants of the

site. A pollen wash of two sandstone fragments and the accompanying sediments was

analyzed from Feature 6, dated to 8150±40 RCYBP, to determine human plant use in the

feature. The sandstone fragments were originally hoped to be groundstone, but upon

inspection after cleaning the matrix from one piece, it was determined to be an unmodified rock.
