POLLEN ANALYSIS AT THE HATCH SITE (5WL38) AND THE BERNHARDT SITE (5WL1860), NORTHEASTERN COLORADO

The Hatch site (5WL38) is located in the Pawnee National Grasslands of Weld County. Deposits identified as Late Plains Woodland were noted. A single hearth yielded a radiocarbon date of 880 + 50 BP (1070 + 50 AD). In addition, occupation zones were also noted and identified as Late Plains Woodland. Pollen samples were examined from the hearth fill, as well as each of two occupation zones. The Bernhardt site (5WL1860) is located approximately 100 meters southeast of the Dent site (5WL269). Relative stratigraphy places this hearth as probable Mid to Late Archaic (4000 to 2000 BP). Pollen analysis of the fill was undertaken to identify any evidence of subsistence activity.
