About this map

The Continental Divide traverses the heart of the central Brooks Range in this mid-century survey, separating the Arctic drainage of the Killik River and Nigu River from the southern-flowing waters of the Kobuk River and Alatna River. This high-altitude wilderness is defined by the massive granite spires of the Arrigetch Peaks and the towering height of Mount Igikpak.

Evidence of human movement through this challenging terrain is found at the Alatna Portage and named crossings like Survey Pass and Kutuk Pass. Large interior water bodies, including Walker Lake and Nutuvukti Lake, serve as primary landmarks in a landscape otherwise devoid of permanent development, save for a solitary Cabin located along the upper Kutuk River. The transition from the Schwatka Mountains to the Helpmejack Hills illustrates the varied topography of the Alaskan interior before the era of modern road infrastructure.
