POLLEN ANALYSIS FOR 24BH2317 AND 24BH2613, SOUTHEASTERN MONTANA

Summary

Both sites 24BH2317 and 24BH2613 are located in southeastern Montana on the west

side of the present Tongue River Reservoir. Site 24BH2317 is a tipi ring campsite located on

the upland, moderately rolling short grass and sagebrush prairie bordering the flooded valley of

the Tongue River. This site appears to have a radiocarbon date of 3930 + 60 BP, indicating a

McKean occupation. Four pollen samples were collected stratigraphically from the fill within

Stone Circle 6 to identify vegetation associated with the occupation and changes in vegetation

from that time to the present. Site 24BH2613 is a single event bison killsite located near the

extreme upper end of the present reservoir. Two pollen samples were examined from deposits

containing bison bone to identify vegetation present at the time of this bison kill, which probably

occurred during the AD 1600s.
