1955 Map of De Long Mountains B-4

About this map

The Kukpuk River winds through this Arctic landscape, creating a dominant drainage system that shapes the local topography. Mapped from 1950s aerial photography by the U.S. Army Topographic Command, the terrain is defined by dramatic elevation changes and sharp landforms such as Spiny Ridge. This mid-century survey captures a corner of the De Long Mountains before modern development, showing a wilderness area devoid of established roads or trails. The intricate contour work illustrates the complex watershed where smaller unnamed tributaries feed into the primary river channel, offering a technical look at the geological makeup of this remote Alaskan region during the early Cold War era of Arctic mapping.
