values for solifl uction sediments: (a) active solifl uction sediments, Banks Island, Canada (French, 1974a), Greenland (Everett,
1967; Washburn, 1967), and Norway (Harris, 1977); (b) relict solifl uction sediments, England (Harris and Wright, 1980; Motters-
head, 1971); (c) relict planar slides in clay, England (Chandler, 1970a, b, Chandler et al., 1976); (d) minimum plasticity and liquid
limit values, Garry Island, NWT, Canada (Mackay, 1981b); (e) range of values reported for near-surface sediments, District of
Keewatin, NWT., Canada (Shilts, 1974); (f) range of values reported for solifl uction lobes in the Swiss Alps (Furrer et al., 1971).
