PHYTOLITH AND STARCH ANALYSIS OF SAMPLES FROM SITES 48CR7309, 48SW16996, AND 48SW17444 ALONG THE OVERLAND PASS PIPELINE PROJECT AREA, WYOMING

Three sites (48CR7309, 48SW16996, and 48SW17444) associated with the Overland Pass Pipeline Post Construction Data Recovery project in Carbon and Sweetwater Counties, Wyoming, yielded samples that were examined for phytoliths and starch. These sites represent occupations between approximately 6500 and 1000 Cal BP. The 79 samples examined represent primarily sediment collected from features and control locations and provide a record of taphonomic processes, dissolution, environment, and economic activity. In addition, two ground stone washes were examined from 48SW17444.

位于怀俄明州卡本县（Carbon County）与斯威特沃特县（Sweetwater County）的奥弗兰德山口管道（Overland Pass Pipeline）竣工后数据恢复项目相关的3处遗址（编号依次为48CR7309、48SW16996及48SW17444），其获取的样本被用于植硅体（phytoliths）与淀粉（starch）分析。
这些遗址的人类活动年代大致介于距今6500至1000校正距今年代（Cal BP）区间内。
本次检测的79份样本主要采集自考古遗迹与对照点位的沉积物，可为埋藏学过程、溶解作用、古环境及人类经济活动提供研究记录。
此外，研究人员还对取自遗址48SW17444的2份磨制石器冲洗样品进行了分析。
