The Yukon-Koyukuk Census Area in northern Alaska is defined by high-elevation terrain and formal land divisions within the Public Land Survey System. This 2017 study details the topography of the Bettles A-2 NE region, where the landscape is organized across the boundaries of T16n R15w, T16n R14w, T15n R15w, and T15n R14w. The map illustrates a wilderness area devoid of modern infrastructure or named settlements, focusing instead on the complex contour intervals that reveal the drainage patterns and peaks of the interior. Prepared using data from the Bureau of Land Management and the National Elevation Dataset, the sheet serves as a primary reference for understanding the physical geography and legal boundaries of this remote subarctic territory.
