The Middle Fork Chandalar River threads through the extreme southwest corner of this sub-arctic terrain, marking the primary drainage in an otherwise high-altitude wilderness. This 2017 study by the U.S. Geological Survey focuses on the complex topography of the Brooks Range within the North Slope Borough, where the landscape is defined by tight elevation contours and expansive ridgelines. The map is primarily organized by the Public Land Survey System grids, specifically tracking the boundaries of townships such as t12s r18e and t13s r19e. Without any roads or human settlements indicated, the map serves as a pure record of the natural drainage patterns and the steep, unpopulated slopes that characterize this portion of northern Alaska.
