AbstractThis predictive surficial geology map is derived from integrating digital datasets of satellite imagery and interpreted air photos. The limit of airphoto interpretation defines training areas where surficial geology map units and landforms have been identified, and used in the generation of the predictive map. Some additional geological features in these areas include small bedrock outcrops, kames, thermokarst depressions, patterned ground, beach ridges, and escarpments. These features may also exist beyond the boundaries of the airphoto interpreted areas. Lakes may include hydrographic layers and mask areas.
Summary(Plain Language Summary, not published)
The map identifies predictive surficial materials and associated landforms left by the retreat of the last glaciers. The surficial geology is based on satellite imagery interpretation and limited fieldwork. This work provides new geological knowledge and improves our understanding of the distribution, nature and glacial history of surficial materials. It contributes to resource assessments and effective land use management.
