Outwash | geology and hydrology | Britannica
outwash, deposit of sand and gravel carried by running water from the melting ice of a glacier and laid down in stratified deposits. An outwash may attain a thickness of 100 m (328 feet) at the edge of a glacier, although the thickness is usually much less; it may also extend many kilometres in length. For example, outwash deposits from the Wisconsin Glaciation
