Big Salmon Fork winds through this interior Alaskan landscape, serving as the dominant geographic feature across a series of township and range divisions. The terrain is defined by the complex drainage patterns feeding into this water body, which cuts a path through the wilderness of the Yukon-Koyukuk region. This 2019 survey by the U.S. Geological Survey provides a clear view of the unoccupied backcountry, where the absence of roads or permanent settlements highlights the isolation of the northern interior. The map focuses on the natural topography and the legal boundaries of the public land survey system, illustrating the vast scale of the Alaskan river systems before they reach more established trading or mining hubs.
