"The glaciated landscape exhibits ice flow features associated with ice advance such as drumlinoids, crag-and-tails and fluted bedrock, which together with striations, record a southwestward ice flow during the last glaciation. Glacially scoured bedrock dominates the area. Discontinuous till veneer is generally restricted to the northeastern map area. Glaciofluvial sediments, including eskers and kames generally trend southwestward. Many eskers consist of a series of short segments. During deglaciation about 11–10 ka BP, fine-grained glaciolacustrine sediments, associated with glacial Lake McConnell, were deposited in many western and southern topographic lows, up to 240 m or possibly higher. Related glaciolacustrine deltas and beaches, marking the decreasing elevation of the glacial lake over time due to isostatic rebound, occur at 270–295 m, although isolated deltas have also been observed at 310, 320, 330 m and as high as 350 m in the northeast. Postglacial eolian sediments exhibit dunes recording both north-northwestward and south-southeastward paleowind directions"--Abstract.
