kame

(geology) A low, long, steep-sided mound of glacial drift, commonly stratified sand and gravel, deposited as an alluvial fan or delta at the terminal margin of a melting glacier.

A round hill or small knoll of sand and gravel, a few meters to more than 100 m high (330 ft). It is one of a family of stratified glacial sediments formed by meltwater in contact with a disintegrating ice sheet. Melting stagnant ice produces large volumes of water carrying boulders, sand, silt, and clay into holes melted in the wasting glacier. When the ice melts completely, the sediment is left standing as small hills. Mixtures of loose rock debris (till) carried above in the melting ice may be lowered onto the kame. Kames are common wherever ice sheets melted, as in New England, New York, the midwestern United States, the British Isles, and Sweden.
