2018 Map of Black River D-6 NW

About this map

Yukon Flats dominates this corner of the Interior, revealing a dense network of water bodies and wetlands characteristic of this vast floodplain. The meandering Porcupine River flows through the southeastern quadrant, joined by the winding Sixmile Slough. This landscape is defined by its complex hydrology, where numerous named lakes such as Sams Big Lake, Moosehorn Lake, and Belle Lake are interconnected by smaller channels and seasonal drainages like Chandalar Cr. The map illustrates the wilderness character of the region, showing how the river systems and stagnant waters of Island Lake and Rock Lake shift across the low-lying terrain. Without roads or permanent settlements shown, the sheet emphasizes the natural geography that has long dictated movement and subsistence in this part of Alaska.
