"The glaciated landscape exhibits large-scale ice-flow features such as drumlinoids, crag-and-tail features, fluted bedrock, and striations that record westward to southwestward ice flow during the last glaciation. Glacially scoured bedrock dominates the map area. Discontinuous till veneer may occur throughout the map area. Glaciofluvial sediments, including eskers, kames, and outwash plains may be part of meltwater corridors, and generally trend westward and southwestward. During deglaciation, which began about 10.5 ka BP, a small number of recessional moraines were formed, and glaciolacustrine sediments, associated with glacial Lake McConnell, were deposited in the southwestern regions. Associated glaciolacustrine deltas and beaches, between 290 m and 330 m elevation, mark the retreating position of the receding ice front over time. Other unrelated isolated deltas have also been observed at 370 m and 390 m. Postglacial eolian sediments exhibit dunes recording both north-northwestward and south-southeastward paleowind directions"--Abstract.
