POLLEN AND MACROFLORAL ANALYSIS AT 48SW11483, THE ALKALI CREEK SITE

Summary

Eight pollen samples and a single botanic identification sample were examined from

48SW11483, the Alkali Creek Site, in Sweetwater County, Wyoming. The Alkali Creek Site is

located on a low ridge overlooking the confluence of Alkali Creek and Salt Wells Creek at the foot

of Pine Mountain between Flaming Gorge and Vermillion Basin. Feature 1, a slab-lined, cobblefilled

hearth, yielded a radiocarbon age of 3580 +/- 70 BP. Features 2 and 3 yielded radiocarbon

ages of 2970 +/- 70 BP and 3360 +/- 80 BP, respectively. These dates define Cultural Component

2, an Archaic Pine spring phase occupation. Feature 4, which was examined in this analysis, was

not radiocarbon dated. A neoglacial soil overlies Component 2. Pollen analysis was undertaken

to identify paleoenvironmental conditions and to examine the occupation surface and a mano from

Cultural Component 1 for evidence of plant processing.
