Moraine
Lake in Banff
A moraine is a mass of rocks, gravel, and sediment deposited by a glacier.
Terminal moraines mark where a glacier's edge once stood; lateral moraines line its sides.
The word appears mainly in geology and geography: The lake formed behind a glacial moraine.
Moraines shape landscapes long after the ice retreats.
