2021 Map of Adak C-5 SE

About this map

Kanaga Island sits at the southern edge of this maritime survey, showing a stark and uninhabited volcanic landscape in the central Aleutians. The island's northern coastline is marked by sharp topographic transitions into Kanaga Sound, where the terrain drops steeply toward the water. Coastal landmarks such as Bridge Point and Cabin Point provide the only navigational markers along this stretch of the Bering Sea. Offshore, the isolated outcrop of Ship Rock stands as a distinct maritime feature in the open water. This 2021 update primarily serves as a record of the shoreline and elevation contours for the northern portion of the island, where the lack of roads or structures emphasizes the island's role as part of a protected wilderness area within the Aleutians West region.
