tion is masked throughout by a mantle of drift of the inner Wisconsin 

 moraine. The island has the general sinuosity of coastline and inequal- 

 ity of topography which would be expected to result from the partial 

 submergence of an irregular ridge,

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.

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 point.
