"The Snowdrift map area is characterized by predominantly glaciated, scoured and washed bedrock terrain. The more elevated areas north and south of the East Arm have isolated deposits of till veneer and blanket. Within the East Arm, some low lying depressions between bedrock ridges are infilled by glaciolacustrine sediments, with various colluvial deposits covering the steepest slopes. Glaciofluvial complexes consisting of eskers, ice-contact sediments and outwash, trend southwestward in the north and westward in the southern map areas. The Snowdrift River valley and its tributaries are predominantly infilled by terraced and floodplain alluvial sediments, and ridged and outwash glaciofluvial sediments, some with active dunes. The last ice flow recorded by glacial striae, fluted bedrock and crag-and-tails, was generally southwestward to westward, in the extreme southeast region of the map area. At various elevations, evidence of glacial Lake McConnell is found: isolated glaciolacustrine deltas at 350 m, 335 m, 320 m, 275 m, 260 m; washing limits at 335 m and 320 m; and raised beaches and wave-cut terraces at 335 m, 320 m, 305 m, 285 m, 228 m, 213 m, 200 m, 183 m and 168 m a.s.l"--Abstract.
