" Lower Jay hill " presents a beach at 1046 feet. This gives upon 

 calculation an uptilt to the shore line of 2.80 feet a mile. The out- 

 let of the lake is not definitely known, but a pass one-half of a mile 

 directly south of Haystack mountain in the Ausable quadrangle 

 (not the mountain of the same name in the Marcy range) has an 

 altitude (1153 feet) that gives the proper figure when the tilting 

 is calculated. When visited, however, this pass did not show evi- 

 dences of stream action. The area is entirely fine sand, but farther 

 north a possible channel, i^ miles north of Bald mountain, is sug- 

 gested as a more probable control.

Following the Wilmington lake, the Upper Jay lake formed in the valley 

 of the East Branch of the Ausable river. The lower levels are not shown 

 in this series. 



Lower phase of the Upper Jay lake. A lower phase of the 

 Upper Jay lake is indicated by beaches on the " Keene hill " at 

 993.9 feet and a beach at 999.5 feet on the slopes of Oak ridge and 

 a level at 1024 feet on the " Lower Jay hill." These figures give 

 the value, 2.75 feet a mile for the tilt. 



Haselton lake. A possible lake with an altitude of 967 feet 

 around the town of Keene has left terraces, wave-cut cliffs and
