156 J. L. Rich — Physiography and Glacial Geology 



In the summer of 1913 the writer tramped from Arkville 

 up Dry Brook, past Furlough Lake, then down into the valley 

 of the Beaver Kill, visiting Balsam Lake, Beecher Lake, and 

 Alder Lake ; thence over the mountain to Arena. During 

 this trip several features were observed which seem to point to 

 local glaciation. Some of them, however, lack the merit of 

 conclusiveness. 



Two miles up Dry Brook from Arkville, a distinct morainic 

 loop over 100 feet high chokes the valley. This is tied onto the 

 hill on the western side in such a way as to indicate that it was 

 formed by a glacier moving down the valley. One mile above 

 Dry Brook village is a considerable mass of moraine also

 at the head of most of the valleys in the vicinity. 



swinging down the hillside on the east side of the valley in a 

 manner indicating ice movement northward down the valley. 

 If the direction of these moraine loops has been interpreted cor- 

 rectly, they unquestionably indicate local glaciation, since the 

 topographic relations are such as to preclude the possibility" of 

 their having been formed by lobes of a southward-moving con- 

 tinental glacier. 



Furlough Lake is a small pond held up by a morainic dam, 

 which the writer could not interpret otherwise than as convex 

 down valley, indicating its formation by a local glacier moving 

 northward. 



On the south side of Mill Brook Ridge is a series of 

 lakes of which three, Balsam, Beecher, and Alder, were visited.
