- Comments
- GhSc-VP: Chuchi Lake: A. Plouffe comments that because of the stratigraphic position of the fossils in lacustrine sediments beneath 'Fraser Till,' the samples give information on the timing of the transition between the Olympia interstade and the Fraser Glaciation. The dates compare well with the date on a mammoth from Babine Lake (34,000 +/- 690 BP). Harington and other report that pollen associated with the Bison latifrons bones indicates an open forest environment. This individual is one of the latest known survivors of its species. Bison latifrons, characterized by large body and extremely long horns, was confined to North America, and lived from at least the second last (Illinoian) glaciation to Late Wisconsinan time. A terminal date between 31 000 and 21 000 is indicated by material from Rainbow Beach, Idaho (Kurtén and Anderson, 1980).
