POLLEN ANALYSIS OF SAMPLES FROM 48NA564, HELL'S HALF ACRE COUNTY PARK, WYOMING

Summary

An alternating stratigraphic pollen column was excavated at Hell's Half Acre County

Park, 40 miles west of Casper, Wyoming. Fifteen pollen samples, including a modern surface

sample, were selected from the column, which represents stratified layers that include multiple

occupations. Radiocarbon ages of 1920 ± 40 BP and 1970 ± 50 BP anchor the lowest

occupation at a depth of approximately 112 cm, while an age of 1320 ± 80 BP ties in the upper

occupation at a depth of 30 cm. Pollen analysis was undertaken to provide information

concerning local and regional vegetation and to provide a reconstruction of paleoenvironmental

conditions at the site. One sample from the lower portion of the stratigraphic column represents

the cultural occupation level. Two samples pre-date this occupation, while the remainder of the

samples represent more recent deposition of sediments.
