Deposits of clay, sand and gravel transported by glacial action and sometimes stratified by running water. (As in the Antler Creek system, there was greater glacial drift than in Williams or Lightning Creeks.)
( Ped.). A general term for the rock debris that has been transported by glaciers and is deposited, either directly from the ice or from the melt water, on melting, of the glacier. It may be heterogeneous or it may be asserted. ( SSSA).
All rock material in transport by glacial ice, and all deposits predominantly of glacial origin made in the sea or in bodies of glacial meltwater, including rocks rafted by icebergs. "Glacial drift occurs as scattered rock fragments, as till [rocks mixed with finer material], and as outwash [fine material with no rocks]. Contrast with angular drift."(from Glossary of Arctic and Subarctic Terms 1955).

is the loose and unsorted rock debris distributed by glaciers and glacial meltwaters. Rocks may be dropped in place by the melting ice; they may be rolled to the ice margins, or they may be deposited by meltwater streams. Collectively, these deposits are called glacial drift. Till refers to the debris deposited directly by the glacier. Rock debris rolls off the glacier edges and builds piles of loose unconsolidated rocks called glacier moraines. Lateral moraines form along the side of a glacier and curl into a terminal moraine.
