GLACIAL PHENOMENA IN MAINE. 133 
tainous ridge. These chains do not run ex¬ 
actly parallel with the coast, their trend being 
more to the north than that of the shore itself; 
so that the ridges extending from east to west, 
across the country, are not exactly at right 
angles with the normal direction of the glacier 
marks, though nearly so. It is this formation 
of the surface of the land which makes the 
glacial phenomena so interesting between Ban¬ 
gor and the sea, especially where one can con¬ 
nect them with like traces farther north. The 
road from Bangor to Mount Desert passes in 
succession over all these ridges, ascending to 
the heights and descending into the interven¬ 
ing depressions ; thus rising three times from 
the bottom of a valley over the ridge interven¬ 
ing between it and the next valley, before 
reaching the southern coast of the large shore 
islands.* Over all the elevations and in all 
the valley bottoms one may trace, in unbroken 
continuity, and almost at right angles with the 
direction of the mountains and of the valleys, 
the same set of lines or glacial marks that we 
have already traced to the north of Bangor, 
running due north and south until they dis-
