Comments
MiVl-1, Ch'ijee's Bluff: This locality is known locally as 12-mile bluff. It is Harington's Porcupine River Locality CRH-100 and Hughes' HH62-228. Two vertebrate specimens found on the river bank at the base of this section have been dated. One of them is a caribou antler wedge (Bonnichsen, 1979: Pl. VIII-19, #109-1) that is dated by RIDDL-141. A bulk sample of silt yielded freshwater shells dated by GSC-952, associated with brown lemming and Arctic grayling fossils and with plant macrofossils indicative of a tundra environment.
