Steep slopes and complex drainages define this interior Alaskan landscape within the Yukon-Koyukuk Census Area. This 2018 survey focuses on the intricate topography of the region, providing a detailed record of elevation and land divisions where human settlements are entirely absent. The map is primarily organized by the Public Land Survey System, showing the convergence of T9n R22e, T9n R23e, T8n R22e, and T8n R23e. Produced by the U.S. Geological Survey using data from the National Elevation Dataset and SPOT imagery, the map documents a pristine wilderness area. For researchers, this document serves as a baseline for the natural hydrology and landform patterns of the Charley River region in the early twenty-first century.
