UPPEK SERIES OP KEENE VALLEY GROUP 657 



and thence through the pass at Boonville. 14 Channels may exist to the 

 west of the Adirondack^ that it will he interesting to correlate with these 

 water levels when investigation is attempted. 



This wide range of levels, as indicated above, leads us to the conclusion 

 that they were not formed by any one lake, but by a series of falling 

 glacial waters; so that the name "Lake Adirondack" is too restrictive. 

 The term "Adirondack Waters" would be more accurate; but as all the 

 waters of the different stages here described are Adirondack glacial waters, 

 it seems desirable to use a more local name, and it is proposed that the 

 term "Saranac Glacial Waters" be substituted for "Lake Adirondack." 

 At least two-thirds of the Saranac quadrangle exhibit sand plains of these 

 waters, the levels of which are so very indefinite that they appear to have 

 been produced in water controlled by ice outlets. Although the drainage 

 may have been westward, as suggested by Professor Fairehild, it is not 

 impossible that the pass, a mile west of Black Mountain — altitude, 1,440 

 feet — was an outlet for this series of water levels to the east, or at least 

 for their lower stages. This possible channel is described in more detail 

 later on. 



Saint Hubert Lake (altitude, 1,300 to 1,340 feet). — There is a small, 

 but finely developed, terrace at the head of Keene Valley, at the point 

 where the Chapel Pond road makes a steep ascent. The altitude is about 

 1,300 feet. The level surface is now used as a base-ball diamond. It 

 was regarded, when first investigated, as the remnant of a morainal lake 

 that was drained by the destruction of the barrier; but more extended 

 field-work soon disclosed some rather ill-defined terraces at the same or 

 slightly higher levels in various portions of the area covered. Among 

 these are a number of terraces and sand plains on the hill traversed by 

 the Keene-Cascade Lakes Eoacl. While the remains of this 1,300-foot 

 level are not as important as those of some of the other glacial lakes, they 

 can not be ignored in a survey of the region. 



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 considerable range to neat, clear-cut 

 deltas, wave-cut cliffs, ^and kame-terraces confined within concise limits. 

 ISTo question can be raised as to their origin. They represent remains of 

 true glacial lakes. The writer believes that when they are better known 

 and appreciated they will be regarded as remarkable and highly in- 

 structive.
