AbstractThe Keller Lake map area contains three glacial terrains. First, ridged and fluted till cover the northeast region above 300 m elevation. Second, streamlined till, including mega-scale glacial lineations, and till plain with an extensive organic cover, dominate a low-lying basin in the north-central and central regions. Third, till blanket, ridged till, and undifferentiated till cover the highlands at 375 to 575 m elevation in the southeast, south, and west. A dominant regional northwestward ice flow first crossed the map area. Subsequently, an ice stream developed late during deglaciation, creating northwesterly oriented mega-scale glacial lineations in north-central regions. Late shifts in ice flow in the northeastern highlands also resulted in west-northwestward flutings superimposed on older northwestward-trending drumlinoids. Retreating remnant ice deposited minor moraines and other ridges over fluted till. In the extreme southeast, glacial Lake McConnell inundated lowlands to 275 m elevation, following retreat of southwesterly flowing ice. Meltwater corridors and glaciofluvial sediments are more prevalent in western regions and record variable flow directions.
Summary(Plain Language Summary, not published)
The map identifies surficial materials and associated landforms left by the retreat of the last glaciers. The surficial geology is based on aerial photograph interpretation. This work provides new geological knowledge and improves our understanding of the distribution and nature of the surficial geology cover, and the glacial history of this region. It contributes to resource assessments and effective land use management.
