PHYTOLITH AND MACROFLORAL ANALYSIS OF FEATURE AND COLUMN SAMPLES FROM SITE 35D061, OREGON

Site 35D061 is located along the North Umpqua River in western Oregon. Paired phytolith and macrofloral samples were examined from column sediments through cultural remains and a feature at this site to identify both past vegetation and human use of plants. All samples were wet when collected and air-dried prior to submission for analysis, making pollen analysis for this material impossible due to modern contamination. The primary research question for this area is the identification of human uses of this watershed during prehistory and up to the present day.35D061号遗址坐落于俄勒冈州西部的北翁普夸河沿岸。研究人员对该遗址剖面沉积物中包含文化遗存与考古遗迹的层位内的成对植硅体（phytolith）、大植物遗存样本开展了分析，以复原该区域的古植被状况，并解析人类对植物的利用模式。所有样本采集时均为湿润状态，且在送检分析前已完成风干处理，受该过程引入的现代污染影响，无法对该类样本开展孢粉分析（pollen analysis）。本区域的核心研究问题为：厘清史前时期直至当代，人类对该流域的各类利用方式。
