Kame

a structure produced by glacial deposition. It occurs as a mound of sands and gravels, with bedding (that is, it is arranged in layers) and often slumping at the sides. It was formed by the melting of stagnant ice which as a result dropped its load of sediment.

A kame is a geological feature, an irregularly shaped hill or mound composed of sand, gravel and till that accumulates in a depression on a retreating glacier, and is then deposited on the land surface with further melting of the glacier. Kames are often associated with kettles, and this is referred to as kame and kettle topography.
