5203 |a"The Curtis Lake south map area is extensively covered by streamlined till, interspersed by bedrock uplands, and by linear glacial troughs in the southwest. Large crag-and-tail landforms apparent on the DEM converge north-northeastward, associated with a major ice stream during the last glaciation. Major changes in ice-flow directions and complex retreat patterns characterized deglaciation. Retreat of ice margins associated with cold-based ice started southward and cold-based, as recorded by abundant lateral ice-marginal meltwater channels found mainly in the north part of the map area. Late during deglaciation, two major ice-flow shifts occurred as a result of drawdown into marine embayments: an eastward flow towards Repulse Bay in the east, and a flow reversal towards Wager Bay in the southwest. Late striations, superimposed streamlined landforms, eskers, subglacial meltwater corridors and channels attest to a warm-based deglaciation in these areas. In the central uplands, retreat to remnant ice masses centred over many of the large lake basins continued largely cold-based, preserving the northward streamlined glacial landscape. The postglacial sea inundated the lowest valleys in the southwest up to 120 m a.s.l."--Abstract.
