2018 Map of Black River C-3 NW

USGS Topo · Published 2018

About this map

The interior wilderness of the Yukon-Koyukuk Census Area dominates this topographic study, characterized by a series of repeating ridgelines and drainage basins. Produced by the U.S. Geological Survey in 2018, the map is organized around the intersection of several land divisions, including T22n R25e and T21n R24e. The terrain represents a complex network of high-elevation points and deep ravines, where the absence of named settlements or roads highlights the isolation of this portion of northern Alaska. The contour lines reveal a landscape of consistent verticality, primarily used for tracking natural drainage patterns and the boundaries between T22n R24e and T21n R25e. This survey serves as a precise record of the topography in a region where few human-made landmarks exist.
