Aniakchak National Monument and Preserve

The Aniakchak caldera stretches six miles wide and 2,500 feet deep, formed by a tremendous volcanic eruption in Alaska's Aleutian Range.

The National Park Service established this protected area in 1978, following decades of geological research in the volcanic region of southwestern Alaska.

Native inhabitants of Aleut ancestry maintain connections to this land, where archaeological surveys reveal patterns of historical human settlements along the coast.

Access requires chartered flights from King Salmon, as no roads reach this remote location, and weather conditions frequently disrupt travel plans.

The monument receives fewer than 100 visitors annually, making it the least frequented site in the United States National Park System.
