- Comments
- EkPg-VP, Milan: Bison and wapiti remains were exposed in a specially dug excavation on the farm of S. Milan. The diamicton overlying the bones was first interpreted as a till, and an age of 22,000 to 23,000 years was expected. The postglacial age of two samples of bison ribs suggests that the diamicton has another origin, perhaps slumped material derived primarily from a till deposited at an earlier date.
