2018 Map of Black River D-4 NE

USGS Topo · Published 2018

About this map

Porcupine River dominates the northern landscape of this Yukon-Koyukuk region, winding through a series of dramatic bends as it flows westward. The waterway serves as the primary geographic corridor through this interior Alaskan terrain, carved by deep valleys and high ridges. Significant elevation changes define the area south of the river, where the drainage of Rat Cr cuts through the uplands. This 2018 U.S. Geological Survey representation emphasizes the natural hydrography and topography of the land, showing the intersection of several townships including t25n r23e, t25n r24e, t24n r23e, and t24n r24e. The map illustrates a wilderness landscape largely defined by its river systems and the absence of established road infrastructure, typical of the remote interior during the early twenty-first century.
