Gatlena Gap defines the interior landscape of this region north of the Tanana Valley, where the topography transitions through several major creek drainages. The map details the winding courses of Fish Cr, which bisects the eastern half of the survey area, and Rogers Cr in the northwest. This 2017 survey emphasizes the natural hydrology and elevation of the Yukon-Koyukuk Census Area, recording a wilderness environment largely defined by its drainages and the high terrain surrounding Gatlena Gap. The absence of roads or permanent structures reflects the remote character of this Alaskan interior during the early 21st century.
