资源简介：
Site 5RB 1872 is a Late Archaic site located near the head of Coal
Draw, an intermittent drainage which flows into East Douglas Creek less
than a mile upstream from the confluence of East and West Douglas Creeks.
Monitoring of bulldozer activity revealed eight identifiable strata of alluvium
and five lenses of charcoal and ash. A single Late Archaic projectile point
base and a quartzite sandstone flake made up the artifact assemblage. A
well constructed fire hearth was noted in the lowest ash lens. Pollen
samples were taken in five of the natural stratigraphic levels, and submitted
for analysis. Pollen analysis at this site was aimed at gathering data to
interpret the paleoenvironment. The natural strata sampled are alluvium
deposited by flooding of the nearby intermittent drainage in Coal Draw
(Martin et al. 1981).
