Summary

The Chance Gulch site, 5GN817, is an 8000 year old camp located about 2.5 miles southeast of the town of Gunnison, Colorado. The site is situated within the sagebrush community, though pine and aspen trees are within view. Nine stratigraphic samples were analyzed to determine paleovegetation and paleoenvironment in the site area and potential plant resources that might have been available to the paleoindian occupants of the camp. Three pollen washes of

groundstone artifacts were analyzed to determine the potential use of plants at the site.

An existing archaeoclimate model based on the 1961 to 1990 monthly climate normals from the Gunnison weather station compared to the stratigraphic pollen signatures noted in this analysis. The single dated stratum, the black mat, at 9560RCYBP will be compared to the modeled precipitation and temperature for Gunnison at 9600 BP, and the date of the cultural occupation will be used to anchor samples to be compared to the model at 8000 BP.
