Abstract
Evidence of several types of glacial lakes is present in the Wager Bay map area. Glacial lakes in the southern half of the map area were small features related to temporary blockage of meltwater by plugs of till or kame. Glacial lakes farther north were more extensive and ice dammed. The largest was an expansion of Brown Lake, marked by large inflow deltas and a sequence of wave-cut notches, whereas finger lakes with deeply incised spillways developed in upland valleys south of Ford Lake. Lake levels fell as successively lower outlets were exposed by the receding ice front. The extent and configuration of the northern lakes require an ice front retreating southeast across Brown Lake as far as the west end of Ford Lake; this ice margin must have formed the west side of a late ice divide. The finger lakes formed subsequently on the eastern side of the ice divide, as a marine calving bay moved west up Wager Bay.
