The interior landscape of the Yukon-Koyukuk region is defined here by the Public Land Survey System boundaries of T19n R21e, T19n R22e, T18n R21e, and T18n R22e. Produced by the U.S. Geological Survey in 2018, this topographic study illustrates a terrain characterized by dense hydrological networks and complex contour elevations, typical of the subarctic wilderness. Unlike many USGS sheets that document human infrastructure, this map reveals a landscape largely devoid of named settlements, roads, or structures, focusing instead on the natural drainage patterns and the underlying township and range grid. It serves as a precise record of the physical geography and administrative divisions within this portion of Alaska shortly after the turn of the millennium.
