About this map

Nunivak Island presents a fascinating volcanic landscape on this remote section of the Bethel Census Area. The topography is dominated by the Ibikwit Lava Bed, a clear indication of the region's geological activity. This terrain is marked by a network of small, scattered ponds and wetlands typical of the Alaskan tundra, centered around the larger Karon Lake. The Duchikmiut River winds through the eastern portion of the sheet, serving as a primary hydrologic feature in an area otherwise characterized by interior drainage and seasonal meltwater. The lack of infrastructure or permanent settlements underscores the isolation of this part of the island, where natural landforms and township boundaries like t2s r99w provide the only points of orientation. This record is essential for understanding the geomorphology of the island's interior before changing climate patterns further alter the delicate permafrost and drainage systems.
