- Comments
- EfQu-10, Blind Bay Rock Shelter: Expectations raised by two projectile points suggestive of Plano affiliation are not supported by the dates. S-725 and S-726, on Zone I, the lowest cultural zone, differ in age more than expected. S-727, from Zone IV, is associated with a small activity area, with a heavy concentration of charcoal containing hundreds of tiny flakes which show signs of heat treatment, or at least of accidental thermal alteration. S-728 was beneath a fallen schist slab in the highest charcoal-stained layer, Zone V.
