- Comments
- GSC-3032 2 HP Comment (R.W. Klassen): The site is on Bostock's (1966) 'Nansen Drift' that he considered to represent the oldest glaciated surface in the region. A date of > 39 000 years (GSC-2817) was obtained in a similar setting in unglaciated terrain about 45 km southwest of this locality. Some of the bone fragments collected on 'Revenue Creek' may be artifacts (C.R. Harington, personal communication, 1979). Comment (W. Blake, Jr.): The sample submitted was a single, tapering piece of wood, approximately 25 cm long and over 5 cm in diameter at the wide end. Both ends were sharp, not rounded, implying little transport despite the absence of bark. The CO2 derived from the first preparation (GSC-3032) was saved and added to the gas obtained from the second burn in order to obtain enough CO2 for the high pressure age determination.
