Kame is a deposit formed by a subglacial stream near the terminal margin of a melting glacier. Streams flowing down mountain sides
onto glaciers deposit sand and gravel at the point where the stream first
reaches the ice, or where the water goes down into a crevasse. The accumulation
of sand and gravel gradually fall down to the valley floor as the ice melts.
Kames are generally small features, 20–30 meters (65–100 feet) in length or breadth. Shapes include hills, mounds, knobs, hummocks, or ridges.
