| Abstract | Surficial mapping in the Cormorant Lake-Wekusko Lake area indicates that numerous and complex ice flow events occurred near the Shield margin area. On the Shield and west of The Pas moraine, which
represents a major glacial landform on the Paleozoic cover, the dominant ice flow trend is south-southwestward, and till composition reflects a northern provenance (Keewatin ice), closely related to the local bedrock. East of the moraine, major ice
flow events trend westerly, and till composition indicates an eastern and distal provenance (Hudson ice). A major late readvance in glacial Lake Agassiz was recorded west of the moraine. Along the Shield margin east of the moraine, this readvance
caused a confluent and parallel ice flow between the two lobes. These events were followed by minor readvances of Hudson ice in glacial Lake Agassiz and against Keewatin ice within a large ice-contact zone at the Shield edge. |
