"Preliminary surficial geology studies, based on air photo interpretation and limited legacy and recent field data, were undertaken in the Joe Lake map area to provide an understanding of the distribution and nature of surficial materials, and regional glacial history. Much of the western area is characterized by streamlined till landforms indicating ice flow towards the north-northwest to north, but locally an older north-northeast flow is crosscut by the younger north-northwestward flow. Similar features occur in the eastern half but are more subdued. Small areas of hummocky till occur in the map area and are associated with longitudinal moraine ridges developed generally parallel to ice flow. Northward flowing subglacial meltwater corridors consisting of eskers, washed till, boulder lags and scoured bedrock, cross the entire area. Glaciomarine deltas, beaches and associated sediments extend up to 160-170 m a.s.l. in the western region, and are found more consistently near 160 m a.s.l. in the eastern half of the map area where these sediments overlie much of the till at lower elevations. The consistency of the elevation of the glaciomarine deltas implies a rapid ice retreat relative to isostatic uplift. There is evidence of glaciolacustrine environments at 170-180 m elevation in the southwest but additional investigations are needed to determine their extent"--Abstract.
