Little Black River winds through this interior Alaskan wilderness, as mapped in a 2018 U.S. Geological Survey project. The landscape is defined by the high-relief topography of the Yukon-Koyukuk region, where the terrain shifts from lower river valleys to ridges exceeding 2,100 feet in the southeastern corner. This survey details the complex hydrography and wetland systems adjacent to the Little Black River, providing an essential reference for the vast, roadless stretches of the Charley River drainage. The map preserves the Public Land Survey System (PLSS) grid, documenting township boundaries including T9N R20E and T8N R22E in a region where physical landmarks are the primary means of orientation.
