2020 Map of Marshall D-3 NW

About this map

The Yukon River dominates this portion of the Kusilvak region, carving a wide, braided path through the low-lying interior. This 2020 survey illustrates the complex hydrography of the river delta system, where large landforms like Hills Island are defined by secondary channels and slow-moving backwaters. One such waterway, Hills Slough, meanders through the eastern section of the map, creating a network of riparian wetlands and small interconnected lakes typical of this subarctic drainage basin. To the west, East Point stands as a distinct topographical marker along the riverbank. The map provides a precise view of the shifting alluvial landscape, showing how the river's historical movement has shaped the contours of the surrounding terrain and created the numerous unnamed ponds and marshy depressions that dot the area.
