Reconnaissance surficial geology, Duggan Lake, Nunavut, NTS 76-H / [by] D.A. St-Onge and D.E. Kerr.: M183-1/113-2013E-PDF
"Preliminary surficial geology studies, based on aerial photograph interpretation and limited legacy data, were undertaken in the Duggan Lake map area to provide an improved understanding of distribution and nature of surficial sediments and regional glacial history. Much of the area is extensively covered by a variety of glacial deposits and landforms, though bedrock outcrops can be found throughout the region. Widespread till veneer, blanket and streamlined till are common in the central and eastern areas, whereas hummocky till occurs in the west. Till-dominated terrain is cut by northwest-southeast trending glaciofluvial corridors consisting of eskers, ice-contact sediments, outwash plains and terraces, and locally elongated zones of scoured bedrock. Small isolated glacial lakes were formed by ponding of meltwater. In the northwest, a discontinuous moraine complex, consisting of glaciofluvial sediments and ridged till segments, forms the western extremity of a major end moraine system referred to as the MacAlpine Moraine. Drumlinoids and striations record a regional northwestward ice flow during the last glaciation"--Abstract.
