1956 Map of Ambler River

About this map

Onion Portage serves as a critical geographic marker along the Kobuk River, signifying a historic crossing and settlement point in this remote Arctic landscape. The mid-century topography reveals a terrain dominated by the towering Brooks Range, where the Schwatka Mountains and Baird Mountains meet. South of these peaks, the remarkable Great Kobuk Sand Dunes and Little Kobuk Sand Dunes create an unexpected desert-like environment amidst the surrounding tundra and river valleys.
