Unimak Island and its southwestern reaches form the geographic heart of this coastal survey. Located within the Aleutian Islands chain, the map details the rugged intersection of land and sea where the Ikatan Peninsula extends toward the vast Pacific Ocean. This 2020 edition provides a modern topographic record of the island's coastal profile, showing the sparse but distinct landforms that define this remote part of the Aleutians East Borough. The survey focuses primarily on the maritime environment and the uninhabited stretches of the island, serving as a critical reference for the complex topography of the peninsula.
