2016 Map of Tanana B-4 NW

About this map

Ptarmigan Cr and Reindeer Cr carve through this interior Alaskan wilderness, defining the drainage patterns of the northern Tanana region. The landscape is characterized by high, unnamed ridgelines and deep creek valleys, with elevations rising sharply toward the east and southeast. This 2016 survey illustrates the remote character of the Yukon-Koyukuk area, where the terrain is marked by the Public Land Survey System grids including T8n R21w and T7n R21w. The lack of man-made structures or roads emphasizes the isolation of these watersheds, which remain primarily defined by natural hydrography and the geometric divisions of the township and range system.
