LOWER KENNEBEC VALLEY SYSTEM. 173 



Short eskers are reported by E. P. Clarke as occurring not far from 

 Sidney Post-Office. They lie more than a mile west of the Kennebec 

 Valley system, and are either local, or, perhaps, branches of this system. 



SHORT ESKERS SOUTH AND SOUTHWEST OF MOOSEHEAD LAKE. 



Several short "horsebacks" have been reported to me as being found 

 in the western part of Shirley, in East Moxie and Bald Mountain towai- 

 ships, and in the western part of Blanchard, near Bald Mountain Pond. 



Near the west end of Kingsbury Pond, in Maytield and Brighton, a 

 series of several gravel ridges comes from the north down a hill into the 

 level ground near the pond. They become reticulated, and then toward 

 the south the ridges become lower and broader and finally coalesce into a 

 rather level delta-plain. The ridges are hardly a mile long, and they appear 

 to be simply a side-hill system. 



Another hillside esker is found on the southern slope of a hill which 

 lies on the north side of Kingsbury Pond, near the line between Mayfield 

 and Kingsbury. The ridge ends near the base of the hill, but does not 

 expand into a delta-plain, unless it be beneath the pond. 



Low passes extend from Kingsbury Pond both north and south, so 

 that all the above-named gravels might possibly form a series connecting 

 either with the Hartland system through Harmony Village, or with the 

 Lower Kennebec system through the west part of Harmony and Athens, 

 or down the Wessen-unsett Valley into Brighton and Athens, or southwest 

 along the valley of Fall Brook toward Solon. I have not explored the 

 country thoroughly. From present information I regard all the short 

 kames above mentioned as local, isolated eskers, not branches of a common 

 system. They were a feature of the last part of the Glacial period, when 

 the ice was retreating northward. 



LOCAL ESKERS IN RICHMOND AND BOWDOINHAM. 



A short ridge of glacial gravel and cobbles is found in the western 

 part of Richmond Village. About 2 miles west of the village, near Abaga- 

 dassett Stream, are a few short, rather flat-topped ridges with no traceable 

 connections. They appear to be small marine deltas. A few miles south- 

 east of this place is an east-and-west ridge of till on the east side of Swan 

 Island, in the Kennebec River. This is probably a small tern:iinal moraine.
