Beautiful Moraine Lake in the Canadian Rockies, with a glacier in the background. A glaciolacustrine environment is merely a fancy term for a glacial lake. First, glaciers form on land in areas where more snow accumulates annually than melts. Glaciers can flow because they are made of ice.
Ice can flow down a slope as water can, albeit at a slower rate.
Sometimes, meltwater from a glacier discharges into a lake. Marine glacial environments, not discussed here, include proximal, continental shelf, and deep-water facies. In contrast, continental glacial environments, specifically, glaciolacustrine facies, will be dealt with. From Benn and Evans, 1998. The major influences on these glacier-fed lakes are the input of meltwater and sediment from the glacier.
