2020 Map of Marshall A-4 NW

About this map

The Izaviknek River meanders across the northwestern corner of this landscape in the Bethel Census Area, marking a transition in an otherwise water-dominant wilderness. This 2020 survey illustrates a complex network of thousands of small unnamed ponds and saturated wetlands that define the Yukon-Kuskokwim Delta region. The terrain is structured by the Public Land Survey System, including T13n R79w and T13n R78w, though it remains entirely devoid of man-made infrastructure or established settlements. The high-density hydrography shown here highlights the seasonal nature of the Alaskan tundra, where the distinction between land and water is often fluid.
