POLLEN ANALYSIS FOR SITES CA-SDI-316, CA-SDI-317, AND CA-SDI-4935B, ALONG THE SAN DIEGUITO RIVER, NORTHERN SAN DIEGO COUNTY, CALIFORNIA

Stratigraphic pollen analysis was undertaken at sites CA-SDI-316, CA-SDI-317, and CASDI-4935B, located within the C. W. Harris Site Archaeological District of the Starwood Project Area in Santa Fe Valley, to identify past vegetation. Pollen samples were collected at 10 cm intervals. In addition, pollen analysis can contribute to an evaluation of the degree of disturbance of deposits containing cultural materials because pollen from plants introduced during the historic era is usually very visible in the upper portion of stratigraphic columns in much of western California. Introduced Eucalyptus and Brassicaceae pollen are expected to be important in evaluating evidence for disturbance. Three pieces of groundstone also were examined for both pollen evidence of plant processing and protein evidence of plant and/or animal processing.

本研究针对位于圣达菲谷星伍德项目区C.W.哈里斯遗址考古区内的CA-SDI-316、CA-SDI-317及CASDI-4935B三处遗址开展地层孢粉分析，以重建区域古植被面貌。研究按10厘米间距采集孢粉样品。此外，孢粉分析还可用于评估含文化遗存的地层堆积的扰动程度——这是因为在加利福尼亚州西部多数区域的地层剖面中，历史时期引入植物的孢粉通常在上层地层中辨识度极高。引入种桉树（Eucalyptus）与十字花科（Brassicaceae）的孢粉，将成为评估地层扰动证据的关键指标。本研究同时对三件研磨石器开展了检测，以搜寻植物加工相关的孢粉证据，以及植物和/或动物加工相关的蛋白质证据。
