Abstract
The distribution of glacial landforms on the northwestern Canadian Shield reflects a complex interplay between dynamic conditions of ice sheets and geology of the beds across which they flowed. To some extent, ice dynamics are reflected in four roughly concentric zones of glacial landforms about the Keewatin Ice Divide (KID), but, in detail, the presence or absence of one form or another often is related to the nature of the entrained debris, and thus, to bedrock geology. The innermost zone, which includes KID, is characterized by featureless till plains and areas of low hummocky moraine. Within it, there is an absence of eskers and ribbed moraine and a paucity of streamlined features. The hummocky surface results from release of debris from the lower parts of an essentially stagnant ice mass.
