1955 Map of De Long Mountains B-5

About this map

The Kukpuk River snakes through the southeastern reaches of this remote Alaskan wilderness, its path carved into the drainage patterns of the De Long Mountains. Produced from 1952 aerial photography and 1955 field annotations, the map reveals a largely uninhabited landscape defined by tight contour intervals and significant elevation changes. The land lines shown here represent unsurveyed and unmarked locations predetermined by the Bureau of Land Management under the Umiat and Kateel River Meridians, highlighting the frontier status of the North Slope during the mid-20th century. This area is characterized by high alpine terrain and numerous unnamed drainage basins that feed into the primary river system, reflecting the untouched character of the region before significant modern development.
