About this map

The Nowitna River meanders through the heart of this interior landscape in the Yukon-Koyukuk Census Area. This remote terrain is defined by its complex hydrography, where the river's winding course creates numerous oxbows and abandoned channels across the low-lying flats. To the west, Pilot Cr joins the larger drainage system, carving a path through the varied elevations that rise away from the river valley. The map provides a precise look at the township and range divisions, including t17s r21e and t18s r22e, which structure this largely untouched wilderness. Geologists and environmental researchers can examine the contour patterns that illustrate the gradual transition from riparian zones to the surrounding uplands in this corner of the Alaskan interior.
