Surficial geology, Ashuanipi River, Newfoundland and Labrador, NTS 23-I southwest / authors, H.E. Campbell, R.C. Paulen, and J.M. Rice. : M183-1/346-2018E-PDF

"The Ashuanipi map area lies south of the ancestral Labrador ice divide of the Laurentide Ice Sheet. The combined record of striations and large-scale streamlined landforms reveal three phases of ice flow (oldest to youngest): northeast, south-southeast, and east-southeast. Erosional and depositional features throughout the map area distinguish the distinct glacial domains. Till veneer with channels and bedrock eroded by glacial meltwater was observed in higher elevation terrain north of Ashuanipi River, and also in the uplands formed by the Paleoproterozoic De Pas batholith to the east. Ribbed moraines, eskers, and streamlined landforms characterize the area southeast of Wade Lake. Extensive lowland fens, glaciolacustrine strandlines, and wave-cut benches that surround isolated streamlined till units in the central portion of the map area mark the former inundation of a large, shallow glacial lake (glacial Lake Low), the basin of which is occupied by the present-day Smallwood Reservoir"--Abstract.
