2015 Map of Ambler River A-5 SE

About this map

The Kobuk River carves a massive, serpentine path through this Arctic landscape, defining the character of the Kobuk Valley National Park in the northwest. This 2015 U.S. Geological Survey representation highlights a transition in the river's course, where it shifts from a broad westward flow to a sharp southern bend, creating significant gravel bars and shifting embankments. Smaller drainages like Omaluruk Cr and Nakochelik Cr feed into the main waterway from the south and east, while Jade Cr enters from the north. The map underscores the dominance of the river system over human infrastructure, showing no established roads or settlements, only the intricate topography and the hydrographic network that has shaped this region for millennia.
