2018 Map of Black River B-6 NW

USGS Topo · Published 2018

About this map

Grass River and the Sucker River dominate this interior landscape in the Yukon-Koyukuk region, illustrating a complex network of meandering waterways and wetlands. The terrain is characterized by intricate oxbow formations and low-lying marshes, typical of the subarctic river systems that define this part of the Alaska wilderness. Small tributaries like Big Cr feed into these larger arteries, while the Little Black River touches the eastern edge of the survey area. There are no roads or permanent settlements indicated, reflecting a landscape shaped almost entirely by natural hydrologic processes. This 2018 survey serves as a modern record of these shifting river channels before any significant human development or infrastructure changed the drainage patterns of the basin.
