- a Perdiz arrow point and a sandy-paste sherd were recovered from about 30 cm above Feature 1 and another Perdiz point came from 20 cm below the feature. Younger radiocarbon age may be from displaced charcoal downward in the profile (same as Perdiz points)- based on the Kelly radiocarbon date guidelines could be AMS from lab name
