POLLEN, STARCH, AND MACROFLORAL ANALYSIS OF SAMPLES FROM HEARTH FEATURES AT SITES 5MF6806, 5MF6871, AND 5MF6872, MOFFAT COUNTY, COLORADO

A total of fourteen samples from hearth features at sites 5MF6871, 5MF6872, and 5MF6806 were examined for pollen, starch, and macrofloral remains. These sites were encountered during well pad construction in Powder Wash, Colorado. Radiocarbon dates suggest Settled Period and Pioneer Period (both Early Archaic) occupations at 5MF6806, Settled Period and Aspen Tradition (Formative Era) occupations at 5MF6871, and Pioneer Period and Aspen Tradition occupations at 5MF6872. Pollen, starch, and macrofloral analyses were undertaken to provide information concerning plant food processing activities at these sites.本次研究对科罗拉多州鲍德沃什（Powder Wash）地区5MF6871、5MF6872及5MF6806三处遗址的14份火塘遗迹样本开展了花粉、淀粉粒及大植物遗存分析。上述三处遗址均在该地区钻井平台施工过程中被发现。放射性碳定年结果显示，5MF6806遗址存在定居期与拓荒期（均属早古风阶段）的人类活动遗存；5MF6871遗址存在定居期与阿斯彭传统（形成期）的人类活动遗存；5MF6872遗址则存在拓荒期与阿斯彭传统的人类活动遗存。本次花粉、淀粉粒及大植物遗存分析工作，旨在揭示上述遗址的植物食物加工活动相关信息。
