- Comments
- MlVl-2, Old Crow River Locality CRH-15: This is one of the few Pleistocene localities in eastern Beringia that has produced multiple vertebrate assemblages in stratigraphic sequence. It has also produced possible evidence of human activity on bones from an erosional contact known as Disconformity A. Of nine radiocarbon dates from CRH-15, the six dates on bone collagen are included in this database. Three of the bones are considered to be possible artifacts because of their fresh-state fractures and well preserved impact scars.
