Kame delta

A kame delta is a glacial landform made by a stream flowing through glacial ice and depositing material (Kame - distinctive because it has been sorted by the action of the stream) upon entering a lake or pond at the end or terminus of the glacier, thus "in front" of it, a proglacial lake. This landform may often be observed after the glacier has melted and usually has a delta (in the sense of the Greek letter) or triangular shape. Often upon melting of the glacier the edges of the delta may subside as ice under it melts and glacial till may be deposited in the lateral or side area also as material is deposited from the melting glacier.
