2016 Map of Ambler River B-2 NW

About this map

The Ambler River winds through the heart of this landscape, its braided channels and gravel bars defining the valley floor within the Gates Of The Arctic National Park. Flanked by high ridgelines, the drainage system is supported by tributaries like Ulancak Cr and Kalurivik Cr, which flow from the steep, contoured slopes of the surrounding Brooks Range. The map illustrates a remote wilderness where the natural hydrology remains the primary structural element, largely undisturbed by infrastructure or permanent settlement. This survey provides a baseline for the northern interior's topography, where elevation changes are sharp and the river serves as the central artery for movement and seasonal environmental shifts in the Arctic.
