5203 |a"The highest central regions of the Erly Lake map area were covered by active ice advancing from the southeast, although exact ages of advance(s) are unknown. Deglaciation of parts of the high interior and southwestern sector of the map area may have started in early Wisconsinan, and may have been free of active ice in middle Wisconsinan time or earlier. Evidence of ice-free conditions is limited. Fluctuating cover of thin ice, probably cold based, may have survived for extensive periods during the Wisconsinan. It disappeared in the Late Wisconsinan, leaving widespread kames and ice-contact deposits overlying surficial sediments and bedrock. Till is widespread at all elevations, and can be variable in thickness, hummocky and makes up moraine ridges and streamlined landforms. In the high interior, it is locally mixed with felsenmeer and isolated kames. Glaciofluvial deposits are concentrated along major river valleys. Postglacial fluvial erosion along the Hornaday River carved bedrock canyons up to 150m deep"--Abstract.
