2018 Map of Coleen B-5 NE

About this map

The northern reaches of the Yukon-Koyukuk Census Area are defined here by a remote and undisturbed landscape, as documented by the U.S. Geological Survey in 2018. The map area is primarily organized by the Public Land Survey System boundaries of T31n R20e, T31n R21e, T30n R20e, and T30n R21e. This terrain is characterized by a dense network of drainages and seasonal watercourses that carve through the interior highlands. Because this quadrant lacks named settlements or developed infrastructure, the map serves as a pure record of the natural topography and the legal cadastral framework that governs this part of the Alaskan wilderness. It provides a precise baseline for understanding the hydrology and land divisions in one of the state's most isolated regions.
