- NbVl-2, Old Crow River Locality CRH-29: This is a final Wisconsinan point bar buried beneath an aggradational terrace. Many species of Pleistocene vertebrates were redeposited onto this point bar between 10,000 and 11,000 years ago when ~Anodonta beringiana< was living in the valley. Paired valves of this large mollusc can be found in growth position among the fossil bones. A small black chalcedony flake was also excavated from this context (Morlan, 1980: 240, Pl. 8.1). There are four dates on three specimens from this locality. RIDDL-133 dates a caribou antler billet to the late Holocene. This billet was found on the surface of the river bank. A second caribou antler with several highly polished facets on its base is interpreted as a pestle (Bonnichsen, 1979: Pl. 8-20; Harington, et al. 1975: 48) and was dated by Chalk River and by RIDDL-230. A large mammal innominate dated by RIDDL-143 was previously considered to be cut-marked (Morlan, 1980: Pl. 4.29), but further study has failed to confirm this interpretation or to indicate an alternative. Both the pestle and the innominate were excavated from the point bar deposits.
