POLLEN, PHYTOLlTH, MACROFLORAL, AND CHARCOAL IDENTIFICATION FOR THE WHITEHURST FREEWAY PROJECT, WASHINGTON, D.C.

Pollen, phytolith, macrofloral, charcoal identification, and/or PET (potentially edible tissue) analyses were conducted on samples from sites 51 NW103, 51NW117, and 51NW117W in the Whitehurst Freeway Project. These three sites are located at the confluence of the Potomac River and Rock Creek in urban Washington, D.C., and represent primarily occupations from approximately 1000 B.C. to the 19th century A.D. The various ethnobotanic analyses were used to provide information concerning plant resources that were available to and utilized by the occupants of these sites.本研究针对怀特赫斯特高速公路项目（Whitehurst Freeway Project）内51 NW103、51NW117及51NW117W遗址的样本，开展了花粉（Pollen）、植物植硅体（phytolith）、大植物遗存（macrofloral）鉴定、木炭鉴定以及潜在可食用组织（potentially edible tissue，PET）分析中的一项或多项。三处遗址均坐落于华盛顿特区城区内波托马克河（Potomac River）与罗克溪（Rock Creek）的交汇处，其遗存年代跨度大致为公元前1000年至公元19世纪，以人类居住活动遗存为主。本次所开展的各类民族植物学分析，旨在为厘清该遗址居住者可获取并实际利用的植物资源相关信息提供支撑。
