LEBANON AND WEST LEBANON SYSTEMS. 263 



plain. Here and there are readies of level osar-plain, but for most of 

 this distance the gravel takes the form of a plain of reticulated kames 

 one-eightli of a mile or more wide. The system passes not far west of 

 Bauneg Beg Mountain, and expands into a marine delta not far north of 

 North Berwick Village. South and east of this point are some discon- 

 tiiuious plains of sand and gravel, but their connectioias are obscure. 

 Maryland Ridge, in Wells, is a large and broad ridge of glacial gravel 

 having a southeast direction. I provisionally mark it as a part of this 

 system, though possibly connected with the great series that extends from 

 Conway and the Ossipee Lake region, in New Hampshire, down the 

 Mousam Valley past Sanford. 



LEBANON SYSTEM. 



A series of somewhat discontinuous and plain-like gravels extends 

 from near Wentworth or Northeast Pond, and in the northwestern part 

 of Lebanon, southward through the central part of Lebanon, following a 

 rather low pass and then the valley of a stream that j^asses near South 

 Lebanon. Toward the south there are several narrow plains, which 

 diverge in direction, as if delta branches of this system. These have been 

 traced by me only a short distance into Berwick. I am. indebted to Mr. 

 J. H. Hammond, of Sanford, for much information regarding this portion 

 of York County. 



WEST LEBANON SYSTEM. 



This gravel system begins on the east side of Salmon Falls River a 

 mile or two north of East Rochester. It crosses into New Hampshire near 

 East Rochester, and is said to extend to Dover, New Hampshire.
