2020 Map of Marshall B-6 NW
USGS Topo · Published 2020About this map
Tungak Lake dominates the central portion of this landscape within the Kusilvak Census Area. This region, defined by the Public Land Survey System grids of T16n R83w and T15n R83w, consists of a complex network of wetlands and small water bodies characteristic of the Yukon-Kuskokwim Delta. The map illustrates a largely unpopulated wilderness where the terrain is shaped more by hydrography than by human settlement, showing the intricate shoreline of the lake and the surrounding marshy lowlands as they were documented in the early twenty-first century. This survey provides a precise record of the natural topography and water distribution in a part of Alaska where shifting wetlands and seasonal changes significantly define the geography.
