of outlets such a simple division is insufficient, so we shall regard 

 the Saranac waters as a series of lakes. The chief cause for the 

 indeliniteness of the levels and the lack of shore-line features must 

 be attributed to the fact that the ice was the barrier in many 

 cases. Many one-bank channels exist, showing that the spillways 

 were constantly being lowered by the melting ice. 



The lower stages of the Saranac waters were chiefly confined to 

 the eastern section, as can be seen from figure 5. 



Eastern section. vS"^ Huberts lake. At a lower altitude than the 

 Saranac water levels there are scattered over the area sloping ter- 

 races of indefinite character that remind the writer of the preceding 

 plains. They are regarded as subordinate in interest to the preceding 

 levels and to those which are described below. There is a small but 

 finely developed terrace at the head of Keene valley at 1300 feet. 

 This level surface is now used as a baseball diamond. Taking this as 

 a starting point the other terraces seem to fit in with the general 

 scheme, and hence there is a possibility of a lake level in the series 

 that once flooded portions of the Lake Placid quadrangle. The most 

 prominent remnant left of this level is on the northeast slopes of 

 Owls Head now traversed by the Keene-Cascade highway. Its 

 outlet was, without much doubt, through the gulf, south of Ellis 

 and Black mountains in the Ausable sheet to the east, the spillways 

 being controlled by one-bank channels which are beautifully shown 

 on the southeast slopes of Black mountain. 



Lower series: confined entirely to the eastern section. 

 In descending from the higher lake levels to the lower ones, the 

 character of the terraces changes from indefinite levels of consid- 

 erable range to neat, clear-cut deltas, wave-cut cliffs and beaches 

 confined within concise limits. No question can be raised as to the 

 origin of many of them. They represent remains of true glacial 

 lakes. 



Wilmington lake. The history of the Wilmington lake is, per- 

 haps, the best understood of all these local lakes. It was chiefly 

 confined to the Lake Placid sheet, to the East branch of the Ausable 

 river, and to the territory around the town of Wilmington; and 

 stretches northward to Lower Jay. (See figure 6.) 



The altitude is iioo feet at the foot of Johns brook in Keene 

 valley where a typical delta was developed. One and one-half 

 miles southeast of the town of Keene, on the state road at Norton 

 cemetery, there is an excellent display of a bisected delta. Around
