About this map

The Innoko River and its meandering tributaries dominate this interior Alaskan landscape, recorded during the mid-1950s. The terrain is characterized by broad, low-lying wetlands and complex drainage systems, where the West Fork Innoko River meets the main channel. Dominant heights such as Lone Jim Mountain and Hunch Mountain provide the primary landmarks in an area otherwise defined by seasonal watercourses like Fourmile Creek and Slane Creek.

Evidence of wilderness transit is found in the established Winter Trail and Tractor Trail, routes that were essential for movement across the marshy lowlands when the ground was frozen or via heavy machinery. These trails signify the remote nature of the region, where infrastructure was limited to seasonal paths rather than permanent roads, reflecting the difficulty of navigating the Yukon-Koyukuk interior during this era of survey.
