GLACIAL GKAVELS OF MAINE. 



This osar is a ridge from 10 to 50 feet high, and north of Levant it 

 has rather steep lateral slopes (see fig. 1 1). It nowhere expands into broad 

 plains, though it is somewhat plain-like south of the railroad in Hermon. It 



begins a few miles south of 

 the high hills bordering the 

 Piscataquis Valley on the south. 

 Except near its north end the 

 series lies wholly in a region 

 that was under the sea. At 

 Kenduskeag Village the lines of stratification of the ridge are much dis- 

 torted, as shown in figs. 12 and 13. 

 Its length is about 25 miles. 



EXETER MILLS-CARMEL BRANCH. 



This branch appears to begin near the northern brow of a hill about 1 

 mile south of Exeter Mills and at an elevation of about 100 feet above that 

 place. The series for sev- 

 eral miles is interrupted 

 by numerous short gaps, 

 yet is easily traceable to 

 South Levant and thence 

 through the eastern part of Carmel to join the Moosehead Lake osar some- 

 what more than a mile north of Hermon Pond station (see fig. 14). It is 

 nowhere a very large ridge, being 10 to 30 feet high. In Carmel it shows 

 several remarkable zigzags (see fig.- 15). It has been imder the sea for 

 most of its course, and is often nearly covered on its flanks by marine clay.

In several places it develops into cones considerably higher than the rest 

 of the ridge. In one place it expands laterally and incloses a deep kettle- 

 hole, and right south of this point is a cone of unusual height. It nowhere 

 expands in broad plains. On the north it begins on the south side of the
