2018 Map of Black River D-6 SW

USGS Topo · Published 2018

About this map

The Porcupine River dominates this landscape of the Yukon-Koyukuk Census Area, winding through a complex network of wetlands and seasonal waterways. The hydrological pattern is defined by dramatic river meanders and long, curving channels such as Ninemile Slough and Sixmile Slough, which illustrate the shifting nature of the arctic river system. Smaller water bodies like Loon Lake and the various branches of the Black River Slough are scattered throughout the low-lying terrain, highlighting a wilderness area shaped entirely by water movement rather than permanent human settlements. This 2018 survey serves as a vital record of the braided river morphology and the extensive wetland environments that characterize this portion of the Alaska interior.
