Ice streams of the Late Wisconsin Cordilleran Ice Sheet in western North America
Abstract The Late Wisconsin Cordilleran Ice Sheet (CIS) of western North America is thought
to have reached its maximum extent (∼ 2.5× 10 6 km 2) as late at c. 14.5 ka. Most (80%) of …

Erosional origin of drumlins and megaridges
The erodent layer hypothesis (ELH) proposes that drumlinization leaves no substantial
stratigraphic record because it is primarily an erosional process that cuts an unconformity …
