- Comments
- Sample was collected from surface in 1991 by Spearman and Birkedal from a cluster of bone northwest of Dune Island A. It is discussed by Vinson in the 1993 report. He identified the specimens as caribou. Field specimens #1 and #2 were combined (tibia and antler) for this date. 111.5 g total weight. 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.
