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.
