KBNDUSKE AG-HAMPDEN BRANCH. 131 



it is overlain by clay. Within a mile south of the village the system comes 

 obliquely down to the shore of the Penobscot River, and its course lies 

 within a broad bay of the Penobscot River from this point to Frankfort 

 Village. It then follows the valley of Marsh River past the bases of the 

 high granitic hills which cluster about Mosqiiito Mountain. From this point 

 southward the gravel contains a large proportion of granite and the ridges 

 become more nearly continuous. Numerous bowlderets appear, and 

 bowlders up to 4 feet in diameter. These in part have till shapes and are 

 floe-bowlders, but many of them are water-rounded and polished on their 

 unweathered surfaces, and are therefore an integral part of the osar. The 

 great size and number of these large rounded bowlders favor the hypothesis 

 that they were deposited in a subglacial channel. The sj^stem passes 

 through Prospect Post-Ofiflce, and then soon turns southeast along the 

 northern slopes of a range of hills. It comes nearly to Gondola Cove, and 

 then turns southward parallel with the Penobscot Bay. As a broad ridge 

 it comes down to the shore of the bay at Sandy Point, Stockton, where it 

 ends in a clifF of erosion at the beach. The bluff here is near 25 feet high. 

 Gravel is reported at Fort Point, in the line of this ridge prolonged. I have 

 examined the deposit and am in doubt whether it is glacial gravel or a 

 raised beach. 



Its length from Moosehead Lake to Penobscot Bay is about 80 miles.

This begins not far north of the south line of Charleston and extends 

 southward through the eastern part of Corinth, then southeasterly to Ken- 

 duskeag Village, where it abruptly turns southwest to Levant Village. It 

 here turns south, and is interrupted by numerous gaps from this point on. 

 It crosses a low col, and at the southern end of the pass it makes a sharp 

 meander almost west for one-fourth of a mile, and then as abruptly turns 

 southward again. The system crosses Hermon Bog and the Maine Central 

 Railroad a short distance east of Hermon station. A continuous ridge 

 extends from the railroad for about 2 miles, where the system becomes inter- 

 rupted by rather long gaps again. This glacial river may have joined the 

 Medford branch near Hampden Upper Corner, but my most recent informa- 

 tion makes it more probable that it joined the main osar river near the south 

 line of Hampden, and that its course lies a mile or more west from the 

 Penobscot. I have not personally explored this series in Hampden.
