About this map

Adak occupies the northeastern corner of this remote Aleutian landscape, where the road network transitions from Happy Valley Road to the Happy Valley Road Detour. The area is defined by a deeply indented coastline and a cluster of maritime landmarks, including Expedition Harbor and the sheltered North Island Anchorage. Topographic detail reveals the steep elevations of Mt Reed and the various points and spits that guard the approaches to the Bering Sea, such as Cliff Point and Chaxchim-gutikix South Spit.

Coastal features like Trappers Cove, Unalga Bight, and Gannet Cove suggest a landscape where maritime access is paramount. The presence of the Sewage Lagoon Road and established island names like Staten Island and Argonne Island reflect the mid-to-late 20th-century development associated with the naval and community history of the region. This 2021 update preserves the exact coastal nomenclature and interior elevation data essential for understanding the island's geography.
