Typical profiles of the continental shelf

Typical profiles of the continental shelf. The vertical scale is greatly exaggerated. This serves to show the variation between a smooth graded slope (Sec. A) and the highly irregular shelf off a glaciated area (Sec. G), 1960, p. 71.

Two types of slide shown schematically

Two types of slide shown schematically. At top three blocks of earth have rotated in clay-water slurry. In the other slide total liquefaction has occurred and water forced out of the clay has formed a pond. The vertical dimension is exaggerated five times. Typical slide has a figure-eight appearance. Material the leaves a hollow at the head region piles up at the foot. The low cliff at the neck is often the bank of a river (Kerr, P.F., 1963, Sci. Amer. Nov., p. 138).

Two samples of quick clay showing contrast

Two samples of quick clay showing startling contrast. Column of undisturbed clay (left) holds 11 kilograms (24 pounds). It can support 2,100 pounds per square foot surface. Another piece of the same clay pours like a liquid afer being stirred in a beaker. No water was added. Demonstration was made by Carl B. Crawford of the National Research Council of Canada (Kerr, P.F., 1963, Sci. Amer. Nov., p. 134).
