The Avgun River winds through this high-latitude terrain, marking a significant hydrologic corridor in the western Brooks Range. This 2015 survey details the intersection of two major administrative regions, the North Slope Borough and the Northwest Arctic Borough, where the boundary cuts across high ridges and deep valleys. A substantial portion of the southern landscape falls within the Noatak National Preserve, a protected wilderness area that remains largely undeveloped and free of modern infrastructure. The topography is defined by sharp contour lines indicating steep slopes and prominent peaks, providing a clear picture of the land's elevation profile during this era. Without roads or permanent settlements, the map focuses on the natural drainage patterns and the precise delineation of Public Land Survey System townships like t32n r14w.
