Topography Such, in fact, has doubtless been its The topography of Fishers island, like its coastline, is highly irreg- ular, its eminences being without apparent system other than the linear arrangement due to the shape of the island. Some of the hills, like those along Isabella beach, have a well marked northeast-southwest trend. At other points, as southwest of Chocomount cove, the hills occur as isolated knobs, or again, as between Hay and West harbor, they occur as somewhat general but broken elevations. ictfS \3i-~~' s0VSD. Figure 2.—Topographic Map of Fishers Island. Scale about 2 miles to an iuch ; contour interval, 20 feet. The general aspect of the topography is decidedly morainal—an appearance which is heightened by the presence of a considerable num- ber of large erratic boulders. An analysis of the topographic features in the field, however, shows that, while there are many minor knobs and numerous basin-like depressions which are sometimes of considerable size and contain ponds many acres in extent, the morainal features are, on the whole, mainly superficial, the broader lineaments of the landscape belonging clearly to an older topography, which in part appears to have been due to subareal erosion, especially at the western end of the island and near Clay 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 Geological Society of America.
