1956 Map of Survey Pass

USGS Topo · Published 1974

About this map

The Continental Divide carves through the heart of the Brooks Range in this mid-century survey, separating the headwaters of several major arctic river systems. To the north, the Killik River and Nigu River flow toward the Beaufort Sea, while the southern slopes are dominated by the Alatna River and the Unakserak River. This wilderness landscape is defined by its high-altitude landmarks, including the towering Mount Igikpak and the distinctive Arrigetch Peaks. The presence of Naval Pet Res No 4 in the northwest corner highlights the federal interest in resource exploration during this era. While formal settlements are absent, a single Cabin label and the Helpmejack Hills area provide rare evidence of human activity in this remote region. The map also documents the Kateel River Meridian boundary, marking a primary survey line through the Endicott Mountains and Schwatka Mountains.
