Surficial geology, Curtis Lake north, Nunavut, NTS 56-I north . : M183-1/204-2014E-PDF
"Much of the Curtis Lake North map area is covered by streamlined till interspersed in the east by dissected bedrock ridges and plateaus, and in the west by boulder-strewn bedrock uplands. Multiple ice-flow indicators reveal a complex ice flow history during the last glaciation and following deglaciation (Figure 1). East of Curtis Lake, the largest streamlined landforms and early striations converge north-northeastward into Committee Bay, associated with ice streaming during the last glaciation. Pervasive north to north-northwestward streamlined landforms associated with late striations formed during deglaciation as the ice retreated southward. Large meltwater corridors carried meltwater northward, infilling north-trending valleys near the head of the Committee Bay drainage basin. Lateral meltwater channels developed in the southern uplands at the margin of cold-based ice remnants. In the southeast, evidence for a late deglacial eastward ice flow reversal is found in the form of weakly fluted till, fine striations, and glaciofluvial sediments"--Abstract.
