Online_Linkage: Description: Abstract: The surficial geology of the Pesh Creek (NTS 94 P/8) map area is dominated by the effects of continental glaciation during the Late Wisconsinan (ca. 25 000-10 000 years ago). In general the ice sheet advanced from the northeast and occupied the broad Shekilie River valley, but at some point, the ice flowed westward across the valley and onto the Etsho Plateau, which borders the western part of the map area. The Shekilie River valley lies about 250 m below the plateau. During deglaciation, when the ice sheet thinned and separated into topographically-controlled lobes, an ice margin within the Shekilie River valley migrated southward and dammed a proglacial lake in the process. This lake migrated southward with the ice margin and eventually merged into glacial Lake Hay. Shekilie River valley is underlain by Cretaceous shale, clayey till and fine glaciolacustrine sediments, which are all poorly drained, and thick organic sediments accumulated over most of the area. Currently, extensive muskeg forms hummocky peatlands which are probably underlain by permafrost and significant amounts of ground ice. Purpose: Supplemental_Information: Data set is in English.
