| 520 | 3 |a"Preliminary surficial geology studies, through aerial photograph interpretation and limited legacy data, were undertaken in the south half of the MacAlpine Lake map area to provide an improved understanding of distribution and nature of surficial sediments, and regional glacial history. Widespread streamlined till, hummocky till with kettle lakes and till veneer which may exhibit small transverse ridges locally, are common across the map area. Some tills are dissected by north-northwestward trending glaciofluvial corridors consisting of eskers, ice-contact sediments, and locally zones of scoured bedrock and lags of till veneer. Isolated glacial lakes of variable extent were formed by ponding of meltwater, and their sediments are now characterized by shallow thermokarst lakes. In the northwest map area, a large moraine complex formed perpendicular to ice flow. It consists of till, major moraine ridges, and glaciofluvial outwash sediments forming part of the western segment of a significant 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. Active eolian activity can occur adjacent to rivers which have reworked and deposited alluvial sediments"--Abstract. |
