Abstract

A variety of processes cause horizontal and vertical movements in mudboils in central District of Keewatin. Differential heaving was found to cause horizontal displacements by inducing creep and by locally concentrating moisture such that gelifluction occurred when the muds thawed. Mudboils immediately upslope and downslope of snow patches, because of excessive moisture, experienced the most rapid surface displacements (0.6 m/year). Caribou migration may be another process responsible for inducing activity from time to time in mudboils over a large portion of central Keewatin.
