﻿JV. S. Shaler — Geology of Cobscook Bay District, Me. 37 



about two hundred miles in length, the length of the shore 

 line, between those points, at high tide, including the coast line 

 of the adjacent islands, probably exceeds three thousand miles. 

 Along this coast region of Maine we find a considerable va- 

 riety in the type of fjord structure. About Portland, within 

 the district of Casco Bay, there are no deep inlets but a profu- 

 sion of small islands. From that bay to the Penobscot the 

 strip-like fjord type of shore, narrow bays with equally narrow 

 promontories, is the prevailing feature. At Mt. Desert the 

 massive crystalline rocks of that region cause the coast to 

 change its character ; the bays or inlets become wider and 

 there is an extensive fringe of islands south of the main shore.

The normal type of fjords is again found on the shore from Mt. 

 Desert to Quoddy Head ; this section differing in no important 

 topographical respect from that between Portland and the 

 Penobscot.
