1956 Map of Howard Pass

About this map

The Brooks Range divides the interior wilderness of the North Slope, where this 1950s topography captures a landscape of extreme isolation and geological significance. Named for the Arctic explorer William L. Howard, Howard Pass serves as a critical mountain gate between the northern plains and the southern river basins. This survey covers the southern portion of Naval Petroleum Reserve No 4, reflecting the era's strategic interest in Arctic energy resources. The terrain is defined by massive ridges such as Monument Ridge and the De Long Mountains, which funnel complex braided river systems like the Kuna River and Colville River toward the Beaufort Sea. Landforms such as The Cockscomb and Rim Butte stand as prominent landmarks for navigation across a roadless expanse. For geologists and researchers, the map documents the primitive drainage patterns of the Etigonik River and Swayback Creek before the impacts of modern development.
