2018 Map of Black River A-4 NW

USGS Topo · Published 2018

About this map

Little Black River winds through the southwestern and western portions of this interior Alaskan landscape, defining the primary drainage pattern for the surrounding wetlands and hills. The terrain is characterized by a dense network of topographic contours and small lakes, typical of the Yukon-Koyukuk region's expansive wilderness. This 2018 survey detail provides a modern look at the remote topography within the Public Land Survey System grids of t16n r23e and t15n r23e. Without established roads or settlements, the map focuses on the natural hydrology and elevation of this subarctic environment. It is an essential resource for understanding the contemporary geography of the region as documented by the U.S. Geological Survey.
