Comments
The sample is a caribou second lower molar (m2) (ID by P. Matheus). It is associated with a microblade core (GAAR 10360) and a black microblade (GAAR 10361). The site consists of a large volume of FCR and faunal remains and some stone tools including lanceolate projectile points, a notched projectile point, microblade cores and microblades, and mitten-shaped burins. More than a dozen radiocarbon dates on bone range from 2530 to 8290 BP. The cultural materials are found largely in a deflated surface context, but intact stratified deposits remain.
