POLLEN ANALYSIS OF GROUNDSTONE AND CHARCOAL IDENTIFICATION AT 48SU1753, SOUTHWEST WYOMING

Summary

Several groundstone artifacts and one charcoal sample were sent for analysis and

identification. The samples were recovered from a slab-lined fire pit during investigations at site

48SU1753 in southwest Wyoming. The radiocarbon dates for the site range from 4280 ± 70 BP

to 1500 ± 60 BP, placing the earlier components of the site in of the Pine Springs Phase of the

Late Archaic and the later components in the Uinta Phase of the Late Prehistoric. The

groundstone artifacts were sent to the lab in order to be washed for any residual pollen and

starches. Depending on the level of preservation, the analysis of pollen and starches might from

groundstones indicates the types of plants that were processed at the site as well as the types

of plants that were available prehistorically in the region. Likewise, the identification of charcoal

will identify the types of trees that were available in the site vicinity and used by groups at the

site.
