About this map

This remote Alaskan interior landscape is defined by the boundary between the Kusilvak Census Area and the Bethel Census Area. The terrain is dominated by an intricate network of wetlands, ponds, and small lakes characteristic of the Yukon-Kuskokwim Delta region. The 2020 data reveals a landscape of nearly pure hydrology, where water and saturated ground outnumber dry land, leaving no named settlements, roads, or man-made structures on the sheet.

Legal divisions are the primary human layer here, with township and range lines like t16n r79w and t15n r78w providing the only reference points for land management. This map documents a wilderness state, where natural hydrographic shifts are more common than human development, serving as a baseline for environmental study and mapping the specific boundary line separating these two census jurisdictions.
