Fic. 38.—A nearer view of the débris-bearing layers which have been curved 
upwards to a nearly vertical position. From a portion of this the discolored surface 
has been cut away to show the difference between the real amount of débris included 
in the ice and the apparent amount deceptively indicated by the surface spreading. It 
also shows the definite arrangement of the internal débris in layers. 
Fic. 39.—A portion of the front of Bryant glacier near the west side of the valley 
showing the inconstancy of the laminations and the formation of a monument of dis- 
colored ice off the face of the wall by the melting or falling away of the ice that once 
surrounded it.
