Aniakchak Bay, Aniakchak National Preserve

Aniakchak Bay, Aniakchak National Preserve

Aniakchak National Monument and Preserve includes the 6-mile (9.7 km) wide Mount Aniakchak Caldera, a collapsed volcano in the Aleutian Range, and the shorelines of Amber Bay, Aniakchak Bay, and part of Kujulik Bay on the Pacific Ocean. This is the least visited unit in the National Park system due to the remoteness and notoriously bad weather.
