Surficial geology, Wholdaia Lake south, Northwest Territories, NTS 75-A south / [Authors: G. Lauzon and J.E. Campbell]. : M183-1/342-2017E-PDF

"Wholdaia Lake south map area is predominantly mantled by thin till and thick till interspersed with organic deposits; outcrop exposure is concentrated in the south and northeast. A network of southwest-trending meltwater corridors, containing eskers and associated glaciofluvial sediments and sandy diamictons cross the territory at regular intervals. Boulder fields surrounding Scott and Wignes lakes mark the paleoshoreline (about 450 m a.s.l.) of a short-lived proglacial lake. Reworked and/or winnowed sediments and paleoshorelines (≤400 m a.s.l.) suggest proglacial lake(s) in the region of Flett Lake–northern Selwyn Lake. Three regional ice-flow directions have been identified. The oldest, poorly defined ice flow is inferred to be to the southeast followed by a regional southward ice flow. Overprinting these is the main southwest ice flow, which is reflected in the landforms. In the Selwyn Lake area, orientation of ribbed moraines and streamlined landforms is consistent with the dominant southwest glacial flow, whereas the northwest map area is characterized by an abundance of streamlined landforms, indicating late rapid glacial flow toward the west-southwest"--Abstract.
