UNRESOLVED

1. Why are there no known pre-Illinoian deposits in Quebec/New England (compared to Midwest)?

2. Why no evidence of weathering or Lake Gayhurst draining between Chaudiere and Lennoxville glaciations?

3. How do multiple till sections in Southern Vermont relate to these in Northern Vermont and Quebec?
