5203 |a"Much of the Walker Lake South map area is covered by streamlined till plains with shallow glacially-eroded basins; however the southeast is dominated by a bedrock highland. Striae and streamlined landforms in till indicate initial north-northeast then persistent northwestward ice flow during the last glaciation, although late-glacial flow reversals occurred to the south and east down glacial troughs in the bedrock highland. Weathered bedrock and regotill indicate areas of cold-based ice conditions and combined with the hummocky till, delineate the presence of late-ice remnants in highlands. Large subglacial corridors containing eskers and other ice-contact deposits carried meltwater northward into the Arctic Ocean. South of the regional drainage divide, short-lived glacial lakes, marked by wave-cut notches and boulder lags on the till surface, developed as the ice front receded southwards into the upland south of the Ford Lake-Wager Bay lowlands. The marine limit ranges from 100–110 m a.s.l. in this area"--Abstract.
