1956 Map of Survey Pass

About this map

Mount Igikpak stands as a focal point in this 1950s survey of the northern Alaskan interior, where the Schwatka Mountains meet the Endicott Mountains within the greater Brooks Range. The landscape is defined by the Continental Divide, which separates the headwaters of the Alatna River and the Kutuk River from northward-flowing streams like the Nigu River. Human presence is sparse, marked only by an isolated Cabin and the Alatna Portage, a historical travel route connecting river systems. The inclusion of the Naval Pet Res No 4 boundary in the northwest corner reflects mid-century strategic interest in the region's resources. The map also captures significant drainage patterns around Takahula Lake and Iniakuk Lake, providing a clear view of the high-altitude topography at Survey Pass and Akabluak Pass before modern development reached these wilderness areas.
