TU 3, S24.34 W0.34, Level 8, 62 "cmb.l.l", Sample #1
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).
