Reconnaissance surficial geology, Carey Lake, Northwest Territories, NTS 65-L / [Authors: D. Maynard and D.E. Kerr].: M183-1/136-2013E-PDF

"Reconnaissance mapping, through aerial photograph interpretation and limited legacy field data in the Carey Lake map area, provides an understanding of surficial sediments and glacial history. The last major ice flow was predominantly westward, as indicated by crag-and-tails, drumlins, and other glacially fluted landforms occurring throughout the map area. Exposed granitic and gneissic bedrock, till veneer, and fluted till dominate the topographically lower region east of Mosquito, Mary, and Gravel Hill lakes. To the west of this series of lakes, hummocky till, till blanket, and large glaciofluvial corridors characterize the landscape. In the shallow basins of these same lakes, fine-grained glaciolacustrine sediments and raised beaches occur up to 320-330 m elevation, and are associated with glacial Lake Thelon. Other glaciolacustrine sediments, found around Carey Lake, as well as to the southwest and southeast, locally overlying areas of ridged till, may relate to an extension of glacial Lake Thelon, an isolated glacial lake, or possibly a phase of glacial Lake Kazan. Areas of organic deposits are presumably underlain by glaciolacustrine sediments, reflecting the uncertainty of glaciolacustrine sediment thickness and extent"--Abstract.
