"Preliminary surficial geology studies, based on air photo interpretation and limited field data, were undertaken in the Daly Bay South map area (NTS 56-A, south) to provide an understanding of the distribution and nature of surficial materials, and regional glacial history. Much of the area is underlain by folded and faulted bedrock containing shallow glacially scoured lake basins. Striae and glacially-moulded bedrock surfaces indicate regional ice flow toward the southeast and late flow south into Daly Bay. Prevalent till veneers and blankets form drumlinoids oriented southeast. Esker systems and substratified deposits developed in well-defined subglacial meltwater corridors oriented parallel to regional and late ice flow directions. Flat-topped eskers suggest they developed late in the glacial cycle, when the ice was thin. Sandy to bouldery marine sediments extend inland to elevations of 140 m (trimline in west) to 150 m a.s.l. (delta in east). De Geer moraines indicate northward ice retreat north of Daly Bay"--Abstract.
