A glacial lake is a body of water that originates from glacial activity. They are formed when glaciers erode the land and then melt to fill the depressions created by the glaciers.

What is a glacial lake and how did it form?

glacial lakes usually formed at the foot of the glacier. As glaciers move and flow, they erode surrounding soil and sediment, leaving depressions and grooves in the land. Meltwater from the glacier filled the hole, creating a lake. Glacial lakes can also form from natural depressions that capture escaping meltwater.

What is Glacier Lake?

In geology, a glacial lake is a lake formed by the damming of melting glaciers, moraine during the retreat of glacial ice dams, or meltwater trapped on ice sheets due to isostatic depression of the crust around the ice.
