﻿Plate 36 



Caved-in roof of a small underground stream in Lowville limestone, 

 nearly 3 miles west of Sanford Corners, Theresa quadrangle, looking 

 north. A good position for the camera could not be obtained so that the 

 view does not exhibit the conditions clearly. The issuing stream shows 

 in the lower left-hand corner. H. P. Cushing, photo, 1907
