Surficial geology, La Biche River northwest, Yukon-Northwest Territories, NTS 95-C/11, 12, 13, and 14 / author: I.R. Smith. : M183-1/455-2022E-PDF
"This map is situated in the Hyland plateau, west of the Mackenzie Mountains, in southeast Yukon. The area was inundated by the Cordilleran Ice Sheet during the Late Wisconsinan glaciation. Ice advanced east to northeast across the rolling bedrock terrain, producing dense networks of sometimes crosscutting bedrock flutings and drumlinoid ridges. During deglaciation, ice flow became increasingly topographically constrained, shifting to more northward flow along major valleys. Meltwater flowing north initially crossed the drainage divide into the Nahanni River basin. Later, as ice retreated south and eastwards, ice-contact deltas and kame terraces formed along the retreating margins. The area is largely covered by till veneer, with bedrock exposed along most ridge crests and glacially incised valley walls. Shale units within the Besa River and Mattson formations are prone to failure, and large rotational landslides are common"--Abstract.
