THE WORK OF GLACIERS 



167 



During the process of the glacial deepening of the Scandinavian 

 fiords the land was higher than now. This was followed by a period 

 of great submergence and later by a reelevation of a few hundred 

 feet. Fiords are common in Greenland, Alaska, British Columbia, 

 southern Chile, and Patagonia. 



Piedmont Glaciers 



When mountain glaciers reach the plain at the foot of the mountains 

 from which they flow, they spread out, as they are no longer confined 

 by valley walls, and coalesce to form piedmont (foot of mountain)
