DESCRIPTION
How do they work? Flow features on the surface may develop from: Deformation of the ice core. Movement of the debris cover along the debris-ice interface. Deformation from a period of glacial advance. Changes in the hydrologic balance. Growth and formation is subject to some debate, with three main theories in prominence: A permafrost origin, which implies that the features are related to permafrost action rather than glacial action; A mass wasting or landslide origin which does not require the presence of ice and suggests a sudden catastrophic origin with little subsequent movement.
