- Comments
- MlVl-3, Johnson Creek Locality CRH-70: The bison bone dated by RIDDL-136 was fractured when fresh, possibly by people (Morlan, 1979: Fig. 6-7). The date is important as a chronological control for the middle of Unit 2b, and it is consistent with a date on associated organic detritus (GSC-2792: >37,000 BP).
