Abstract
In the Schultz Lake area, faceted and striated bedrock surfaces and palimpsest streamlined landforms record multiple ice flows. An old southeastward flow across the area was followed by a north-northwestward flow and a late westward ice-streaming event. In the Wager Bay area, striations and glacial landforms are less developed. In the northern parts of this area, flow was to the north-northwest, with late flows into Wager Bay. In the south, flows shifted between southward and southeastward. A central 20 km wide belt of weathered upland terrain has few striae or glacial landforms. Although both areas lay beneath the Keewatin Ice Divide during the last glaciation, ice-flow directions, sequences, and glacial landscapes are different. Mobile, wet-based ice and a shifting ice divide characterized the Schultz Lake area. In contrast, the ice divide at Wager Bay seems to have been fairly stable and could have been cold based prior to deglaciation.
