Definition A drift topography characterized by chaotic mounds and pits (generally randomly oriented) developed in supraglacial drift by collapse and flow as the underlying stagnant ice melted. Slopes may be steep and unstable, and there will be used and unused stream courses and lake depressions interspersed with the morainic ridges. Characteristically, there are numerous abrupt changes (lateral and vertical) between unconsolidated materials of differing lithology.
