MACROFLORAL ANALYSIS OF SAMPLES FROM THE DUTCH CREEK SITE (5JF463) , COLORADO

Proposed construction of a bike path bridge over Dutch Creek resulted in
Test pit excavations of the impacted areas at Site 5JF463. This site is a
prehistoric campsite containing at least three cultural components located near
Denver, Colorado. The 1992 test pit excavations yielded cultural deposits dating
to approximately 4210 BP, suggesting a Middle Archaic occupation. Feature fill
from Test pits 1 and 2 was sampled for macrofloral remains to provide possible
subsistence information.

因计划在荷兰溪（Dutch Creek）上方修建自行车道桥梁，科研人员对5JF463遗址的受影响区域开展了探坑发掘工作。该遗址坐落于科罗拉多州丹佛市周边，为一处史前营地遗址，至少包含三处文化遗存单元。1992年实施的探坑发掘出土了可追溯至约距今4210年的文化堆积，表明此处曾存在中古风期（Middle Archaic）的人居活动。科研人员对1号与2号探坑的遗迹填充物进行了采样，以提取大植物遗存，为复原先民的生计模式提供参考依据。
