2020 Map of Kwiguk D-4 SW

USGS Topo · Published 2020

About this map

Nunachik Pass and Kwikpak Pass define this water-dominated portion of the Kusilvak Census Area, where the shifting channels of the Yukon River delta create a complex maze of wetlands and seasonal ponds. The landscape is characterized by a dense network of hydrologic features, with nearly every square mile saturated by the low-lying coastal terrain. As part of a contemporary 2020 study by the U.S. Geological Survey, the map provides a precise record of the current shoreline and channel positions within this dynamic delta environment. The lack of named settlements or man-made structures on this sheet underscores the isolation of the region, highlighting instead the raw, unpopulated geography of the Alaskan tundra and its intricate waterway systems.
