Fig. 5 The Glacial Lake succession in the Lake Placid quadrangle. 



Stage four. 



With the opening of the glacial channels in the Ausable sheet the Lower 

 Newman Lake was succeeded by the Saranac glacial waters, the late 

 stage of which is indicated on the map. The altitude of this series of 

 lakes range from 14410 to 1660 feet, although the level shown is that at 

 1500 feet. 



There is a decided " gap " in the sand plains in the Saranac levels 

 at about 1550 feet, and thus it would be proper to subdivide the 

 lake into upper and lower phases, but as the lake had a succession
