Abstract
The Kazan Upland, the only surface exposure of Precambrian Shield found in Alberta, was extensively scoured by the Laurentide Ice Sheet during the last glaciation and is now sparsely covered by glacial deposits. In contrast, areas underlain by Paleozoic sedimentary rocks west of the Slave River are covered by widespread glacial, deltaic and lacustrine sediments. The ice sheet flowed southwestward over the area during the last glacial maximum, but the pattern of ice flow changed during deglaciation when two distinct lobes developed. A westward-flowing ice lobe, occupying the Lake Athabasca basin, converged with southwesterly-flowing ice north of it. The lateral contact between the two lobes is marked by converging striae and a broad east-west band of glacial outwash and lake sediments.
