Archaeological Data Recovery at the Harrower Site (48SU867): Labarge Natural Gas Project, Appendix E: Pollen Analysis

The Harrower site (48SU867) is located along both sides of Dry Piney Creek in the Overthrust Belt of Sublette County, southwestern Wyoming. This multicomponent site exhibits cultural material dating between 13,620 B.P. and 280 B.P. Pollen samples from a stratigraphic column were collected and analyzed at 5 cm intervals and represent the paleoenvironment from approximately 12,000 B.P. to 9000 B.P., and 3300 B.P. to the present. In addition, a single sample from the moss underlying this column was examined. The age of this moss was established as 13,620 B.P. The pollen recorded from this stratigraphic column addresses the paleoenvironment for these periods. In addition, several features and a piece of ground stone were analyzed for their pollen content to provide data concerning subsistence at this site.

哈罗尔遗址（48SU867）坐落于怀俄明州西南部萨布利特县逆冲带内的干松溪两岸。该多组分遗址出土的文化遗存年代跨度介于距今13620 B.P.至280 B.P.之间。研究人员以5厘米为间隔对一根地层柱中的花粉样品开展采集与分析工作，这些样品可反映距今约12000 B.P.至9000 B.P.、以及距今3300 B.P.至现代的古环境状况。此外，研究人员还对取自该地层柱下方苔藓层的单一样品进行了检测，经测定该苔藓样品的年代为距今13620 B.P.。该地层柱所记录的花粉数据可阐释上述时段的古环境信息。同时，研究人员对多处考古遗迹及一件磨制石器的花粉含量进行了分析，以此获取该遗址生业模式相关的研究数据。
