WebbA good example is the Downie Slide, a translational slide north of Revelstoke, BC, which is shown in Figure 15.9. In this case, a massive body of rock is very slowly sliding down a steep slope along a plane of weakness that is caused by the foliation in the rock. The foliation is approximately parallel to the slope. WebbSlump is a type of slide (movement as a mass) that takes place within thick unconsolidated deposits (typically thicker than 10 m).
