1986 Map of Hughes B-1

About this map

The Koyukuk River winds through this interior Alaskan landscape, defining the topography between the Klaluthyiit Bluff and the prominent heights of Kohokachalla Mountain. This mid-1980s provisional study, based on 1970s aerial photography, documents a remote riverine environment where human presence is marked only by a solitary Cabin along the main channel and a Tractor Trail cutting through the terrain. The hydrological network is dense, featuring the confluence of the Mentanontli River and several drainages such as Discovery Creek and Slathlouka Creek. The map provides specific detail for river navigation and bush travel, identifying features like Curve Slough and Dog Island, alongside large water bodies like Lake Nogrilenten. This is a landscape where natural drainage and elevation dictate movement, offering researchers a clear look at the wilderness before modern shifts in the river's course.
