1956 Map of Ambler River

About this map

The Brooks Range dominates this mid-century survey, where the rugged peaks of the Baird Mountains and Schwatka Mountains define the northern Arctic landscape. In the southern portion of the map, the Ambler River and Kogoluktuk River flow toward the Ambler Lowland, a region marked by significant mineral exploration at Bornite and the Partner Mine. This period of mapping captures the wilderness before extensive modern development, highlighting traditional transit points like Onion Portage on the Kobuk River and specialized terrain such as the Great Kobuk Sand Dunes. Remote outposts are noted by scattered cabins and the Ambler Landing Area, while the North Slope Borough Boundary marks the political division across the high alpine passes of Ivishak Pass and Nakmaktuak Pass.
