ABSTRACT/DESCRIPTION:    
Selected major rivers were extracted from all rivers and streams in the USGS I :2,000,000  
Digital Line Graphs (DLG) dataset. The major rivers include the Copper, Susitna, Kuskokwim,  
Yukon, Koyukuk, Kobuk, Noatak, and Colville Rivers. To access the complete statewide DLG  
dataset. please refer to the documentation for the theme, "Rivers." For details on the source, please  
refer to the publication below.
