DEFINITION OF KAME

A glacial landform such as a low mound, knob, or

ridge composed of stratified fluvial/glacial sand and gravel,

deposited by a glacial stream. Some kames form as deltas or

fans along the margins of deltas, others form in low spots

beneath glaciers, and still others form in ponds on the glacial

surface or on stagnant ice left by retreating glaciers. Kames

may occur in groups, forming kame fields, or as a long line of

kames along the front of a stagnant glacier, leaving a kame

moraine behind when the glacier retreats. Kame terraces consist

of stratified fluvial/glacial sand and gravel deposited

between a glacier and a valley wall, commonly left standing

as a ridge on and parallel to the slope of a valley wall separating

unglaciated topography above from the glaciated valley

floor below.
