THE GLACIERS 35 



Glacier in Alaska, which, near the front, flows at a 

 rate of from five to ten feet in twenty-four hours. 

 Mount Shasta has three glaciers, but Mount 

 Whitney, although it is the highest mountain in the 

 range, does not now cherish a single glacier. Small 

 patches of lasting snow and ice occur on its northern 

 slopes, but they are shallow, and present no well 

 marked evidence of glacial motion. Its sides, how 

 ever, are scored and polished in many places by 

 the action of its ancient glaciers that flowed east 

 and west as tributaries of the great glaciers that 

 once filled the valleys of the Kern and Owen's 

 rivers.
