1956 Map of Black River B-3

About this map

The Salmon Fork Black River and the Black River dominate this interior landscape, weaving through the expansive Yukon Flats of eastern Alaska. Mapped from aerial photography in the mid-1950s, the terrain is defined by a dense network of meandering waterways, wetlands, and small lakes characteristic of this alluvial basin. The absence of roads or permanent structures on the sheet reflects the wilderness character of the region, which is largely contained within the National Wildlife Refuge. In the southwest corner, the map shows Whitefish Lake situated along the river's path, while the Grayling Fork Black River enters from the southeast. This survey provides a baseline view of the complex river systems before the minor revisions of the late 1980s, serving as a critical reference for understanding the hydrological patterns of the northern refuge.
