- Comments
- Charcoal sample from 62 cmbd in Test Unit 3. Sample underlies a stemmed projectile point (YUCH 3013) and should provide a maximum age for that item. Both this sample and the projectile point underlie a volcanic ash layer presumed to be the White River Ash. The eastern WRA lobe formed ca.1140 years B.P. (Clague et al., 1995).
