Abstract

Hummocky or disintegration moraine is a widespread late Wisconsin glacial terrain type across the glaciated Great Plains of mid-continent North America. This terrain consists of chaotic hummocks and enclosed kettle hollows that are widely underlain by clay-rich till. In this paper, the AA. test the postulated subglacial origin of hummocky moraine using a geotechnical model of a deforming soil (till). The model confirms that hummocky topography can be the result of failure and deformation of fine-grained till by differential loading below stagnant ice
