2020 Map of Black A-1 NE

USGS Topo · Published 2020

About this map

Black River meanders through this portion of the Kusilvak Census Area in western Alaska, defining a landscape of complex hydrology. The map illustrates a dense network of unnamed wetlands, thaw lakes, and sloughs characteristic of the Yukon-Kuskokwim Delta. This terrain is marked by the Public Land Survey System boundaries of t25n r86w, t25n r85w, t24n r87w, and t24n r86w, which provide a geographic framework for an area devoid of permanent road infrastructure or named settlements. For those studying the environmental history of the Alaskan bush, the shifting course of the river and the intricate lake patterns offer a look at the region's natural drainage before significant modern human intervention.
