Surficial geology, northwest Smallwood Reservoir, Newfoundland and Labrador, NTS 23-I southeast / [authors, R.C. Paulen, J.M. Rice, and M.B. McClenaghan]. : M183-1/315-2017E-PDF
"Approximately 60% of the map-area is covered by the Smallwood Reservoir, created in 1974 with the damming of the Churchill River at Churchill Falls. The terrain is of moderate relief, with higher elevation regions in the northeast that correspond to the southern extent of the Paleoproterozoic De Pas Batholith and Late Archean Orma domain intrusive rocks. Three general phases of ice flow are observed in the map-area: to the northeast, southeast, and east. Meltwater corridors and eskers crosscut the southeasterly oriented glacial landforms and drained to the southeast and east towards the former ice margin. A large shallow glacial lake filled the Smallwood Reservoir basin. This glacial lake was previously unmapped. This lake is herein informally referred to as ‘glacial Lake Low’ named after A.P. Low of the Geological Survey of Canada, who first recognized that the final disintegration of the continental ice sheet occurred in this region"--Abstract.
