About this map

The confluence of the Middle Fork Koyukuk River and the South Fork Koyukuk River dominates this subarctic landscape during the early 1970s. The map illustrates a region where geography is defined by seasonal movement, shown through the extensive network of Winter Trails that navigate the valleys between significant peaks like Twelvemile Mountain and Cathedral Mountain. Human presence is sparse, centered primarily around small outposts like Tramway Bar and isolated Cabin locations along the waterways.

Drainage systems such as Slate Creek and Rosie Creek flow from higher elevations through gaps like Rosie Creek Pass and Sitkum Pass, illustrating the complex watershed of the Brooks Range foothills. Distinctive landforms such as Chapman Island and the sharp Cliff near Eagle Creek serve as critical navigational markers in a wilderness largely devoid of permanent roads. This 1970 survey records a transition period in Alaskan land management, with lines predetermined by the Bureau of Land Management for areas that remained unsurveyed on the ground.
