Reconnaissance surficial geology, Jervoise River, Nunavut, NTS 66-E, north half / [by] D.A St-Onge and D.E. Kerr ; cartography by F. Fortin.: M183-1/131-2013E-PDF
"Preliminary surficial geology studies, through aerial photograph interpretation and limited legacy data, were undertaken in the north half of the Jervoise River map area to provide an improved understanding of distribution and nature of surficial sediments, and regional glacial history. Widespread till veneer, hummocky till and streamlined till are common across the map area. Some areas of till are dissected by north-northwestward to northward trending glaciofluvial corridors consisting of eskers, ice-contact sediments, outwash plains, and locally zones of scoured bedrock. Small isolated glacial lakes were formed by ponding of meltwater, and their sediments are now characterized by thermokarst terrain. In the central area, a discontinuous moraine complex, consisting of glaciofluvial ridged sediments, ice-contact outwash plains and till ridges, forms part of the western segment of a major end moraine system referred to as the MacAlpine Moraine. Drumlins and crag-and-tails record a regional north-northwestward ice flow during the last glaciation. Rivers have reworked and deposited extensive alluvial sediments"--Abstract.
