2018 Map of Black River A-2 NW

USGS Topo · Published 2018

About this map

Grayling Fork Black River meanders through this remote portion of the Alaskan interior, showing the complex hydrology of the Yukon-Koyukuk region. The landscape is defined by the winding course of Bull Creek, which cuts through the survey area and illustrates the shifting drainage patterns characteristic of the northern wilderness. This 2018 survey provides a clear view of the undeveloped terrain as it existed in the early 21st century, dominated by the natural waterways and the legal grid lines of the Public Land Survey System, including t16n r27e and t16n r28e. The lack of named settlements or infrastructure highlights the isolation of this river valley, making it an important reference for understanding the primitive state of the land before any modern human encroachment.
