Surficial geology, Kangiryuaqtihuk/Minto Inlet, Northwest Territories .: M183-1/51-2011E-PDF
"In Minto Inlet, continental Laurentide ice flow was northwesterly, as recorded to the east and north of the inlet by crag-and-tails, striations, till lineations including drumlins, and eskers. Deglacial drawdown to a westerly flowing Minto Inlet glacier led to scouring by glacial ice and meltwater which stripped till and exposed bedrock. Till is calcareous, incorporating local igneous rocks with a few shield erratics. To the north of the inlet where flow was less active between the Minto glacier and the northwest flow, massive till deposits still contain buried glacier ice. There are numerous gravelly kames and kettle lakes, as well as thaw flow slides in these ice-rich sediments. Under an area of northeasterly ice flow northeast of the head of the inlet, ponding of meltwater permitted rapid ice flow which created till lineations. Postglacial marine overlap has left discontinuous flights of raised beaches on exposed coasts, and thick silty glaciomarine sediments around embayments on the northwest shore of the inlet"--Abstract.
