POLLEN AND MACROFLORAL ANALYSIS AT SITE 48SW7935, WASHAKIE BASIN, WYOMING

Site 48SW7935 is one of three sites in southern Wyoming involved in data
recovery for the Questar Pipeline Coipany Skull Creek Pipeline. Excavations at
this site uncovered two hearth features that were sanpled for pollen and
macrofloral remains. An uncorrected radiocarbon. date of 5210 + 100 BP was
obtained frem.Feature 5, suggesting an Early Archaic occupation. Pollen and
macrofloral analysis is used to provide subsistence information at this site.
In addition, a modern surface soil sample was collected to provide a control for
interpreting pollen samples from the features.

48SW7935号遗址是怀俄明州南部参与奎斯塔管道公司（Questar Pipeline Company）斯库尔克里克管道（Skull Creek Pipeline）项目考古数据抢救工作的三处遗址之一。该遗址的发掘揭露出两处火塘遗迹，并对其采集了孢粉（pollen）与大植物遗存（macrofloral remains）样本。研究人员对5号遗迹测得未校正的放射性碳定年（radiocarbon date）结果为5210±100 BP（Before Present，距今），表明该遗址存在早古风期（Early Archaic）的人类定居活动。孢粉与大植物遗存分析旨在获取该遗址的生业模式相关信息。此外，研究人员还采集了现代表层土壤样本，作为解读该遗址遗迹内孢粉样本的对照样本。
