| Abstract | Reconnaissance mapping, through aerial photograph interpretation and limited field and legacy data in the Beaverhill Lake map area, provides an understanding of surficial sediments and glacial history.
The last major ice flow was westward, indicated by glacially fluted landforms, although local minor southwestward and northwestward flows are recorded. An earlier west-southwest flow is inferred from streamlined features and erosional troughs
observed locally. Major glaciofluvial corridors indicate a westward meltwater flow, debauching locally into glacial lakes in the central and northeast regions, representing various phases of glacial Lake Thelon. Glaciolacustrine regression beaches
occur around Beaverhill Lake and elsewhere, at and below 340 m a.s.l. The extensive muskeg deposits in the north central regions are remnants of this glacial lake, and occur at elevations up to 365 m or possibly higher. The lake sediments are mapped
as organics, presumably underlain by glaciolacustrine sediments, and glaciolacustrine veneer over till, reflecting the uncertainty of glaciolacustrine sediment thickness and extent. |
| Summary | (Plain Language Summary, not published)
The Beaver Hill map (NTS 75-I) identifies surficial geology and associated landforms left by the retreat of the last glaciers which covered the area
about 9000 years ago. The surficial geology is based on aerial photograph interpretation and fieldwork. This work provides new geological knowledge and improves our understanding of the distribution, nature and glacial history of surficial
