Book excerpt: This study presents new measurements of glacial lake levels in the Wager Bay map sheet (National Topographic System 56 G), which includes the head of Wager Bay, Ford Lake, and Brown Lake. Two main types of glacial lakes are described in this paper. The first are proglacial lakes, where sediment-laden melt water that flowed down the natural slope of the land was obstructed by till or kame dams. The second are ice-marginal lakes, where water bodies were trapped between a major ice margin and the hillsides. The paper summarizes the main characteristics of each type.
