Penobscot bay, Maine, is a triangular embayment, whose inland apex is the mouth of the Penobscot river, and whose base toward the sea is 30 miles across.* The bay opens to the Atlantic, and the nearest land to the southeast is that of South America and Africa, more than 4,000 miles distant. In the mouth of the bay are many islets and several islands among them the Fox islands,† to which this note specially refers. The features here discussed relate to wave sculpture and ice sculpture, and a brief account of the topography is accordingly appropriate.
There are two of the Fox islands, as distinguished from islets, North Haven and Vinal Haven, the former lying north of the latter and being separated from it by the Fox Islands thoroughfare, a narrow strait. Their extent is about 10 miles from north to south . . .
