Gates of the Arctic National Preserve dominates the western portion of this terrain, where the high ridges of the Brooks Range drop into the northern tundra. The landscape is defined by the glacial drainage of the Itkillik River and the Atigun River, illustrating the stark divide between protected wilderness and the industrial infrastructure necessary for northern resource extraction. In the southeastern corner, the concentration of the Alaska Pipeline and the Dalton Highway represents the primary corridor for trans-Alaska transport. This 2017 survey shows the modern alignment of the haul road and pipeline as they parallel the Atigun River valley, providing a precise record of the human footprint within the otherwise undeveloped North Slope Borough wilderness.
