About this map

The Seventymile River carves through this northern Alaskan landscape, serving as the primary drainage for a network of creek systems often associated with early mining activity. This mid-century survey reveals a remote wilderness where industry is indicated by a Placer Mine near Easter Creek and a Landing Strip positioned for access to the high northern terrain. Evidence of seasonal transport is visible in the Tractor Trail that meanders alongside the main river valley.

The topography is dominated by prominent summits such as North Peak and various ridge systems like Alder and Granite. The map details a dense hydrology including Bonanza Creek, Independence Creek, and Mogul Creek, which flow through deep valleys. These watercourses and the surrounding peaks define an area where human presence was limited to specialized aviation, trails, and mineral extraction during the 1950s.
