"Preliminary surficial geology studies, through aerial photograph interpretation and limited legacy data, were undertaken in the north half of the Pelly Lake map area. Widespread streamlined till blanket, hummocky till, till veneer and ridged till which may exhibit small transverse ridges locally, are common across the map area. Drumlinoids and crag-and-tails record a regional north-northwestward ice flow during the last glaciation, with local crosscutting age relationships. Rare morainal ridges indicate recessional or stagnant ice-marginal positions. Northward trending meltwater corridors consist of glaciofluvial sediments, zones of scoured bedrock, lags of till veneer and areas of ridged till. Isolated glacial lakes of variable extent were formed by ponding of meltwater, and some fine-grained glacial lake sediments are now characterized by shallow thermokarst lakes. Previous levels of Pelly and Garry lakes are estimated on ice-contact deltas at 190–200 m a.s.l. Active eolian activity can occur adjacent to rivers and lakes, associated with glaciofluvial sediments"--Abstract.
