Abstract
Streamlined landforms are prevalent in the northwest and central regions, interspersed between zones of till and ridged and hummocky till elsewhere. Small moraines west of Lac la Martre form ridges parallel to fluted landforms, and some are dissected by meltwater corridors. Eskers trend southwestward with a few exceptions. Glaciolacustrine sediments, associated with glacial Lake McConnell, occupy poorly-drained low-lying areas of the southernmost map area. West of Lac la Martre and Bartlett Lake, some glaciofluvial sediments and bedrock ridges were reworked into glaciolacustrine beaches between 270 and 300 m a.s.l. In southern regions, extensive organics with thermokarst are common. A northwestward ice flow in northern and central regions is overprinted by a younger and weaker westward flow. Southwestward and westward ice flow is recorded in eastern and southern regions. Larger moraines near the intersection of these flows may mark the retreat of ice margins or stagnating lobes.
