7. ALASKA 



By W. H. Osgood 



i. general 



Alaska has an area of 590,000 sq. mi. 

 or about one-fifth that of the United 

 States. The main part of it lies between 

 the same parallels of latitude as the 

 Scandinavian Peninsula. Its shores are 

 washed on the north by the Arctic Ocean 

 on the west by Bering Sea, and on the 

 south by the Pacific. Its coastline is 

 ver}- long and much indented, and there 

 are many outlying islands. It is largely 

 a mountainous region, although flat- 

 lands of considerable area are found on 

 its northern coast and about the deltas 

 and in parts of the vallej's of its larger 

 rivers. In general, the mountains are 

 in two series, northerly extensions of 

 the main continental systems. The 

 Pacific or Coast system follows the coast 

 and curves southward to include the 

 .Aleutian Islands. The Rocky Mountain 

 system, continuous from Canadian terri- 

 toiy, is parallel in general trend with the 

 coast system but separated from it bj^ 

 a wide plateau through which course 

 Alaska's two greatest rivers, the Yukon 

 and the Kuskokwim. 



Notwithstanding its great area and 

 its complex topographic features, in- 

 cluding the highest mountains in North 

 America, the greatest glaciers, and 

 some of the largest rivers and forests,
