About this map

Untouched interior wilderness characterizes this portion of the Black River A-4 NE quadrangle within the Yukon-Koyukuk Census Area. The terrain is defined by a dense network of elevation contours and natural drainage patterns, organized by the Public Land Survey System into townships including t16n r24e and t16n r25e. This map documents a high-latitude landscape where no permanent roads or settlements were recorded by the Alaska Department of Transportation or the GNIS at the time of publication.
