"The Walmsley Lake map area is characterized by three broad zones based on distribution and nature of surficial sediments. In the north, hummocky till with a few isolated subdued moraine ridges, and smaller areas of till blanket dominate the landscape. The central area is defined by extensive regions of hummocky till in the east, and till blanket in the west. The southern regions consist of a combination of till blanket, till veneer, hummocky till and bedrock, the latter becoming more prevalent to the west. Tills are locally dissected by glaciofluvial corridors consisting of eskers, ice-contact sediments and scoured bedrock. These features record a westward meltwater paleoflow in the eastern regions, and a northwestward flow in the western regions. The earliest ice flow, defined by rare striae in the north, was southwestward. The last, dominant ice flow forms a partial radiating pattern defined by striae, fluted bedrock, crag-and-tails and drumlinoids. Ice flow was northwestward in the north and central regions, becoming west-southwestward in the south, though minor variations are found locally"--Abstract.
