- Comments
- DdRu-VP, Saanich Peninsula: The gravel containing a mammoth humerus is the Quadra Sand of Clague (1977), earlier called the Saanichton gravel by Halstead (1968). Harington comments that Clague (1977) had noted that the Quadra Sand is older than 29,000 years at the north end of the Strait of Georgia, but is younger than 15,000 years at the south end of Puget Sound. GSC-2829 is in accord with the relatively late dates expected for organic material in Quadra Sand in such a southerly location. It provides the first indication of the geological age of Pleistocene land mammals on Vancouver Island.
