Stability of Slopes in Frozen Soil, Mackenzie Valley, N.W.T.
A field study of landslides has shown that certain types of mass movement in the Mackenzie Valley, N.W.T. are associated with shear failure in frozen soil. These land-slides have been classified on a descriptive basis as being block and multiple retrogressive slides. A detailed description of the ch...
