GLACIAL GEAVELS OF AIAINE. 



favorable slopes in order to climb hills, and are therefore difficult to map. 

 Delta branches are liable at any point to diverge from the series one is 

 exploring, and constant watchfulness is required. 



The map shows the com-ses of these connected series more clearly 

 than any verbal description, yet in the absence of maps showing the relief 

 forms of the land it may be best briefly to describe the glacial gravels of 

 three townships as a specimen of the whole region now under consideration. 



Near the southern end of the Fryebui-g Valley the glacial gravels 

 begin, and extend southward along a low pass between the conical peaks

known as Tibbitts and Peavys hills. The line of gravels ihen descends 

 about 100 feet into the east-and-west valley of Pequawket Stream. It 

 here divides into three delta branches. One series crosses the valley 

 nearly at right angles and ascends the long hill which lies to the south 

 along the south branch of Pequawket Stream to a height of fully 2C0 feet. 

 Another branch turns east and follows the Pequawket Valley through 

 Brownfield Village, when it soon expands into a broad plain reaching to 

 East Brownfield, southeast of which place it becomes confluent with the 

 gravels of the Albany-Saco River series. This plain shows the horizontal
