Introduction 

 g en era l fea t ures 



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,t 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. 



TOPOGRAPHY OF FOX ISLANDS 



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 and 18 miles from
