Outside the glaciated areas, along the southern California coast, the continental shelf proper is restricted to a narrow coastal strip, 2 to 25 km wide. Outside this shelf, however, a continental borderland may be defined as a basin and range province, including 14 basins the bottom depths of which range from 627 to 2571 m, and the sill depths from 475 to 1902 m (Revelle and. erN 4°E Fig. 4. Continental shelf near Bergen, Norway, with longitudinal depressions. Transverse depression at entrance to fjords. (After H. Holtedahl, 1955.) Shepard, in Trask, 1939; Shepard and Emery, 1941; Emery, 1954, 1960). The basins are often steep-sided troughs. The intervening ranges, which run parallel to the coast in a NW-SE direction, include islands with fringing submerged shelves. Finally, a typical continental slope is found after the outermost ridge is crossed. There are various elevations on the continental shelves, of the same types as those rising from the adjacent mainland. The hummocky topography in the Gulf of Maine strongly resembles the glaciated landscape in North-east Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hill, M.
