Comments
JjVi-7, Chimi: Component 1, situated above White River ash, is assigned to the Aishihik phase, the late prehistoric antecedents of the Athabaskan residents of the area. Component 2, situated below White River ash, is assigned to the Taye Lake phase. GSC-940 and GSC-941 indicate that there was a time lapse of about 4000 years between the draining of glacial lake Sekulman-Aishihik and the beginning of occupation at this site. Workman considered GSC-956 to be anomalous, because it is younger than the overlying ash layer. However, Blake (GSC-X: 481) noted that this date corresponds closely with several others on the east lobe of the White River tephra. Component 3 is a lower peat deposit within the lacustrine clay at the bottom of the site. It yielded unidentified animal bones, non-diagnostic artifacts, and one radiocarbon date (S-1281).
