1956 Map of Ambler River

About this map

Ambler River and the Kobuk River systems converge in this Alaskan wilderness, defining a landscape of broad lowlands and high peaks within the Brooks Range. The settlement of Ambler sits near the junction of these waterways, serving as a focal point for the Ambler Lowland. This mid-century survey documents a region defined by its geology and conservation importance, featuring the Jade Mountains and the unique geography of the Great Kobuk Sand Dunes. Evidence of mineral exploration and traditional use is found at Mine and Onion Portage, while towering summits like Bismarck Mountain and Cosmos Mountain anchor the horizon. The presence of several Cabins and a Landing Strip underscores the remote character of transportation before the formal establishment of the surrounding national parks and preserves.
