Reconnaissance surficial geology, Hardisty Lake, Northwest Territories, NTS 86-C / [Authors: D.E. Kerr and H.B. O'Neill]. : M183-1/337-2017E-PDF
"The glaciated landscape of the Hardisty Lake region of the Northwest Territories exhibits striations and large ice-flow features such as drumlinoids, crag-and-tail features, and fluted bedrock that record westward to southwestward ice flow during the last glaciation. Glacially scoured bedrock, with till-veneer patches in depressions, dominates much of the map area, but extensive till deposits occur in the more elevatedregions of the southwest. Glaciofluvial landforms, including eskers, kames, and outwash plains, are part of poorly defined meltwater corridors, and generally trend southwestward. During deglaciation of the map-sheet area, which began about 10.5 ka BP, a discontinuous line of recessional moraines was created east of Rebesca Lake. Glaciolacustrine sediments, associated with glacial Lake McConnell, were deposited inthe central and western regions. Associated glaciolacustrine deltas and beaches occur between 210 m and 310 m elevation, but washing limits are found as high as 340 m locally on the eastern flanks of the till highlands"--Abstract.
