2018 Map of Black River D-6 SE

About this map

The Porcupine River sweeps through the northern reaches of this Yukon-Koyukuk interior landscape, defining a complex hydrography of shifting channels and low-lying basins. The terrain is characterized by a dense network of water bodies, where the Black River Slough and various isolated basins like Schrader Lake and Rock Lake illustrate the seasonal pulse of an Arctic river system. Further east, a cluster of named water features including Willow Lake, Mud Lake, Cabin Lake, and Scotty Lake suggests a localized drainage pattern typical of the region's wetland environment. This 2018 survey by the U.S. Geological Survey documents the unpopulated wilderness near the Canadian border, where the absence of roads and human structures highlights a landscape shaped entirely by natural alluvial processes and permafrost hydrology.
