1956 Map of Fort Yukon B-1

About this map

Grass River winds through this interior Alaskan terrain, defining a landscape dominated by complex waterways and wetlands. Surveyed in the mid-1950s, the area shows the intricate drainage patterns of the Sucker River and an extensive network of unnamed lakes and marshes. A single Tractor Trail cuts across the southeast, providing a rare mark of overland passage through this saturated environment. The mapping reveals the isolation of the Yukon-Koyukuk region before significant modern development, where transportation relied heavily on these seasonal trails and the winding river corridors that dictate the movement of people and resources in the bush.
