CANADIAN LANDFORM EXAMPLES ‐ 17 RETROGRESSIVE THAW SLUMPS
Retrogressive thaw slumps are the most active geomor‐phic features of permafrost terrain (NRC 1988). Also called ground‐ice slumps (Mackay 1966), they consist of a layer of ice‐poor overburden, an ice‐rich face and a low‐angle mudflow downslope (figures 1 and 2). They are common along northern river...
