About this map

Koyukuk stands at the strategic confluence where the Koyukuk River meets the Yukon River, serving as a vital focal point in this 1952 aerial-based survey. The landscape is defined by an intricate network of waterways and shifting islands, including Koyukuk Island and Megotsol Island, separated by channels such as Holtilyet Slough. The settlement itself features essential mid-century infrastructure, including a Landing Strip, Tanks, and the Koyukuk Azimuth Mark, reflecting its role as a transportation and navigation hub in the Alaskan interior.

Evidence of earlier communication networks remains visible via the Abandoned Telegraph Line cutting across the northern terrain. The map also delineates the extensive boundaries of the Innoko National Wildlife Refuge and the Koyukuk Nat Wildlife Refuge, protecting the vast wetlands and sloughs like Patsy Slough and Happy Slough. Local historical details are preserved through the marking of a Cem and various isolated Cabins, providing insight into the sparse but permanent human presence along these major river arteries.
