5203 |a"Preliminary surficial geology studies, based on air photo interpretation and limited field data, were undertaken in the Overby Lake map area to provide an understanding of the distribution and nature of surficial materials, and regional glacial history. Much of the western area is characterized by rubble-covered bedrock containing shallow glacially scoured lake basins. Streamlined rock and till landforms indicate ice flow towards the northwest and north-northwest. Till blankets and veneers have a pebbly silty-sand matrix, but their surfaces tend to be bouldery where they were affected by glacial meltwater. Subglacial meltwater corridors consisting of eskers, washed till, boulder lags and scoured bedrock, cross the entire area. The MacAlpine Moraine in the southeast formed during glacial recession about 8200 years ago, and is defined by hummocky till, kames, and related glaciofluvial outwash. Sandy postglacial marine sediments extend up Ellice River to 220 m a.s.l. In the northeast, below 190 m a.s.l., silty marine deposits form extensive plains between drumlinoid ridges in the Queen Maud Bird Sanctuary"--Abstract.
