About this map

Cape Avinof projects into the coastal waters of southwest Alaska, marking a significant geographic point where the Bering Sea meets the Etolin Strait. This 2020 survey illustrates a highly dynamic maritime environment characterized by a fragmented shoreline and the presence of offshore features like Fingurbek Island. The map data, synthesizing hydrography from the National Hydrography Dataset and satellite imagery, reveals the complex interactions of tide and silt along this portion of the Bethel Census Area.

Inland from the cape, the landscape is dominated by the marshy lowland characteristic of the Kuskokwim Delta. While modern in its production, the sheet preserves the essential coastal topography that has dictated navigation and subsistence patterns for generations in this remote coastal reach. The absence of roads or established settlements within these particular township lines underscores the persistence of a wilderness landscape shaped by the sea.
