资源简介：
Two small samples from Ditch Creek were examined for datable carbon. Sample 40
yielded sufficient Alnus charcoal to date, but sample 35 exhibited no charcoal large enough to
date. Therefore, an extraction of microscopic charcoal (micro-charcoal) was conducted to
obtain a sample of sufficient size to date.
