onward movement was so much smaller as to give almost no 
visible signs of motion at the margin. Some motion is, of 
course, implied by the very existence of the glacier and its lateral 
moraines. The absence of appreciable disturbance of any kind 
is notable because it betrays the sluggishness of the glacial

activity. So slight was the evidence of motion at the front of 
the glacier that I was prompted to resort to the closest avail-

in the edge of the ice and accurately measuring with a steel 
tape line the distance from it to a fixed object in front of the 
glacier —but unfortunately no opportunity to return and make a 
second measurement was afforded.
