"Reconnaissance mapping, through aerial photograph interpretation and limited legacy field data in the MacKay Lake map area, provides a basic understanding of surficial sediments and glacial history. The region appears to have experienced more than one ice flow, but fluted till and crag-and-tails record a dominant last, southwestward flow. Bedrock is well exposed in some areas of the northeastern and extreme southeastern regions of the map area. Elsewhere, extensive till deposits occur, with variable surface expressions. Till blanket and till veneer are common throughout the map areas, whereas morainal deposits appear in the central regions and increase in importance towards the south and west. Glaciofluvial complexes and corridors consisting of eskers, ice-contact sediments and scoured bedrock, record a generally west-southwestward meltwater flow across the map area during deglaciation. A few raised beaches and trim lines along the shores of MacKay Lake range from 410 to 440 m elevation. Their limited extent may suggest confined ice marginal glacial lakes during deglaciation"--Abstract. Includes abstract in French. gccst Geological maps gccst Lakes gccst Surficial geology Canada.
