Proglacial lake

Lake formed by the action of ice

In geology, a proglacial lake (ice-marginal lake), is a lake formed either by the damming action of a moraine during the retreat of a melting glacier a glacial ice dam, or by meltwater trapped against an ice sheet due to isostatic depression of the crust around the ice. At the end of the last ice age about 10,000 years ago, large proglacial lakes were a widespread feature in the northern hemisphere. They have become an increasing feature in areas such as Greenland with potential importance in raising sea levels.
