1955 Map of De Long Mountains B-2

About this map

The De Long Mountains dominate this remote Alaskan landscape, as documented by the U.S. Geological Survey using mid-1950s aerial photography. This high-altitude terrain is defined by its drainage systems, where the headwaters of the Kukpowruk River flow northward and the Wulik River carves a path through the southern foothills. Notable landmarks like Sheep Mountain and Chevron Hill provide topographic anchor points in a region that, at the time of field annotation in 1955, contained no established roads or trails. The map reveals the intricate network of alpine drainage, including Wrench Creek, illustrating the natural conduits through the Brooks Range before modern infrastructure or mineral exploration reached this part of the North Slope.
