2018 Map of Black River D-3 NW

USGS Topo · Published 2018

About this map

Rat Cr flows through this interior landscape of the Yukon-Koyukuk Census Area, where the topography transitions from wetland basins to elevated ridges. The map details the surveying boundaries of the t25n r24e, t25n r25e, t24n r24e, and t24n r25e townships. This 2018 survey provides a modern snapshot of a vast and largely uninhabited region in eastern Alaska, emphasizing the natural drainage patterns and the precise elevation contours that define the local watershed. The absence of named settlements or infrastructure highlights the remote character of this subarctic wilderness, serving as a baseline for researchers tracking environmental changes or exploring the hydrography of the Black River region.
