POLLEN ANALYSIS OF SITE 48SW1393, SWEETWATER COUNTY, WYOMING

Fourteen pollen samples were selected for pollen analysis from site 48SW1393 in Sweet Water County, Wyoming. This site is located approximately 600 meters east of the confluence of Deadman Wash and Tenmile Draw, and extends 450 meters south of this point. The site is situated in an extensive stabilized dune complex in a large valley or floodplain area associated with Deadman Wash and Tenmile Draw drainages at an elevation of 6560 feet. This floodplain is generally characterized by low relief, although the entire area is surrounded by steep escarpments, which are typical of the Rock Springs Uplift region.本研究从怀俄明州甜水县（Sweet Water County）的48SW1393遗址中选取14份花粉样本用于花粉分析。该遗址位于死人冲沟（Deadman Wash）与十英里冲沟（Tenmile Draw）汇流点以东约600米处，且以此为基点向南延伸450米。遗址坐落于一片广袤的固定沙丘复合体中，所处区域为与死人冲沟、十英里冲沟水系相关联的大型山谷或漫滩地带，海拔为6560英尺。该漫滩整体以低起伏地貌为主要特征，但整片区域被陡峭的崖壁环绕，这也是罗克斯普林斯隆起区（Rock Springs Uplift）的典型地貌特征。
