The Bering Sea dominates this maritime survey, illustrating a critical stretch of the Aleutian chain where the northern waters meet the protected reach of Akutan Bay. The map focuses primarily on open water and the administrative limits of the Aleutians East Borough, though the southeastern corner provides a detailed look at the rocky shoreline of Akun Island. Compiled from 1983 aerial photography and edited in 1989, this provisional study reflects the navigational and jurisdictional complexities of the region at a time when precise shoreline mapping was vital for the fishing and transport industries in the Aleutians. The boundary between the sea and the bay is marked as indefinite, capturing the fluid nature of these subarctic coastal environments.
