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.
