About this map

The waters of the Bering Sea dominate this coastal landscape, where a network of tidal channels and passes dissects the low-lying shoreline. This 2020 topographic record of the Kusilvak Census Area reveals a complex aquatic environment where the Kutnuknuk Channel and Acharon Channel facilitate the movement of water through the coastal marshlands. The presence of Flat Island in the northeast corner serves as a primary landmark in an otherwise fluid terrain of shifting silt and tides.

Waterborne transit is clearly the defining characteristic of this region, as shown by named waterways like Kwemeluk Pass and Kiangolevik Pass. These features represent the essential arteries for travel and subsistence in a part of Alaska where traditional road infrastructure is absent. The map provides a precise view of these vital hydrographic features at the start of the 2020s, documenting the intricate boundary between land and sea.
