2017 Map of Kantishna River B-4 NW

About this map

The Bitzshtini Mountains dominate the western portion of this Alaskan interior landscape, where steep ridgelines give way to the winding course of the Cosna River. Flowing across the southern and eastern reaches, the river establishes a sharp contrast between the high terrain and the lower drainage basins characteristic of the Yukon-Koyukuk region. This 2017 survey reflects the remote, roadless character of the territory, defined by the Public Land Survey System grids of t5s r22w, t5s r21w, t6s r22w, and t6s r21w. The topography reveals the complex drainage patterns of a subarctic environment, where the elevation drops from the summits of the Bitzshtini Mountains toward the alluvial valleys of the Cosna River, providing a clear look at the geological transitions within this unpopulated wilderness.
