"Preliminary surficial geology studies, based on air photo interpretation and limited recent field data, were undertaken in the south half of the Armark Lake map area to provide an understanding of surficial materials and regional glacial history. Much of the map area is covered by till veneer and swaths of sandy till with streamlined forms indicating ice flow to the NNW. Till blankets contain material derived from Thelon sandstone bedrock south of the map area, although till veneers are derived from more local bedrock. Subglacial meltwater corridors, spaced across the area, are also oriented NNW. An extensive, sandy kame moraine, characterized by kettle topography and kame terraces, marks a recessional ice margin on the north side of Garry Lake. Short-lived ice-marginal and proglacial lakes covered much of the terrain below an elevation of 220 m, leaving flat sandy deposits with thermokarst depressions and tundra ponds. The most extensive glacial lake deposits lie north of the kame moraine"--Abstract.
