1956 Map of Black River B-1

About this map

John Roberts Cabin stands as a solitary named human landmark in this 1950s survey of the remote eastern interior of Alaska. The landscape is defined by the winding course of the Black River and its significant tributary, the Salmon Fork. As the terrain reaches the eastern edge of the sheet, the international border is marked by a series of boundary monuments, including Mon 71 and Mon 72, delineating the United States Canada line. The intricate drainage network of Drifting Snow Creek, Runt Creek, and Racquet Creek reveals a complex system of marshes and high-latitude wetlands characteristic of the Yukon basin before modern development. This map captures the area in a purely wild state, recording only the most essential geographic markers and an isolated trapper or traveler shelter.
