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.

Somewhat haphazard distribution of sediment types on the shelf off San Diego, California. Shepard, 1960, p.86.

Submarine canyons. A. The hypothetical termination od a submarine canyon part way down the continental slope. B. The actual relationship of the submarine canyons to the continental slope with valleys continuing beyond the excavated portion of the canyon down the floor of the deep-fan. Shepard, 1960, p. 154.

Topography off the outer Mississippi delta, 1940. Small landslide gullies move forward with the advance of the Mississippi Delta over the continental slope. They do not extend down the slope deeper than 200 feet. Shepard, 1960, p. 133.

Gorda Escarpment. Showing the displacement of the submarine contours off northern California where the San Andreas Fault may bend seaward. According to this hypothesis, the Gorda Escarpment resulted from the seaward shift of the area tot he south. The dots are earthquakes epicentres and the accompanying numbers are magnitudes on the Richter Scale, which measures the intensity of earthquakes according to their damage to structures. It will be noted that the large earthquakes (6 and over) are concentrated along this escarpment. Shepard, 1960, p. 125.

Inselbergs of batholithic rocks on a rejuvenated erosion surface, Madagascar. The crystalline floor has been bevelled by a vast erosion surface that is slightly rejuvenated as indicated by the rivers which begin to cut down. On the surface lies a group of Inselbergs whose steep slopes form a clearly visible angle with the erosion surface. They are residual hills of harder rocks belonging to an oval shaped batholith the outline of which is indicated by the drainage. Erosion of this group was clearly fracture-controlled. In places the erosion surface penetrates into the group and all the batholithic rock has been removed. France Institut Geographique National. Relief form atlas, 1956, p. 103.
