| Abstract | Preliminary surficial geology, based on airphoto interpretation and limited legacy field data of Bloody River map area, records a dynamic Late Wisconsin glacial landscape. Streamlined till and bedrock
landforms, relating to Laurentide ice originating east of the map region, indicate regional westward flow diverged northwestward and southwestward at the eastern end of two topographic highs. Ice then converged between and south of these two highs,
then diverged at the western end of these highlands. During deglaciation, ice stagnated in northwestern and central highland regions, forming extensive hummocky moraine, large kames, recessional moraines, and kame moraines. In other parts of the map
area, hummocky till, small moraines, and undifferentiated till ridges, were deposited over fluted till. Outwash plains, eskers, and meltwater corridors record northwestward to southwestward meltwater flow. Glaciolacustrine sediments associated with
glacial Lake McConnell occur in the southeast, up to 280 m elevation. Other unrelated, isolated glaciolacustrine deltas indicate small ice-marginal lakes between 400 and 460 m elevation. |
| Summary | (Plain Language Summary, not published)
The Bloody River map (NTS 96-P) identifies surficial materials and associated landforms left by the retreat of the last glaciers. The surficial geology
is based on aerial photograph interpretation, with striations from a previous publication. 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. |
