"Yellowknife Bay was covered by the Laurentide Ice Sheet, with generally southwestward ice flow, during the Late Wisconsinan glaciation until about 10,000 BP. With ice retreat, Glacial Lake McConnell inundated the area, which was replaced by ancestral Great Slave Lake as water levels declined. Surficial geology includes widely-exposed bedrock, and a dominance of fine-grained sediments within low-lying areas deposited within deep glaciolacustrine and shallow post-glacial lake settings. Other sediments include extensive subaqueous outwash deposits of sand and gravel, re-sorted at the surface by wave-action. Wave-washed bedrock is also common, with occasional perched boulders on bedrock and little if any exposed till. Vegetation consists mainly of open to dense forests of black spruce, jack pine, and paper birch mixed with marshes, fens and peat bogs in low-lying areas. Permafrost is extensively discontinuous in the area, occurring within most organic deposits as well as alluvial and glaciolacustrine sediments"--Abstract.
