1955 Map of Kateel River C-5

About this map

Koyukuk National Wildlife Refuge dominates the northern reaches of this Alaskan interior landscape, a region defined by its complex hydrologic patterns and the imposing Continental Divide. The survey details the winding course of the Kateel River as it meanders through the lowlands, joined by the South Fork Huslia River. This 1950s documentation of the Yukon-Koyukuk region highlights a wilderness prior to modern environmental classifications, though updated to reflect federal reservation boundaries established in 1980. The intricate contouring illustrates the transition from the river basin to the high ridge lines that separate major drainage systems in the Alaskan interior.
