Mount Amukta

Mount Amukta is an active stratovolcano on a circular island in the Four Mountains chain. The peak rises about 3,500 feet above sea level, and the island itself measures roughly 8 kilometers across.

The volcano experienced a series of documented eruptions between 1786 and 1791, representing its first recorded period of intense activity. This timeframe provides the earliest scientific observations of its behavior.

The Aleutian Islands, including Mount Amukta, represent generations of indigenous Aleut people who developed methods to survive in this volcanic environment.

Access requires specialized travel arrangements, including flights from Anchorage followed by boat navigation through coastal waters. Visitors should expect challenging weather conditions and limited accessibility.

The volcano sits on an arcuate ridge trending east to west, suggesting the presence of an ancient caldera roughly 6 kilometers across. This geological structure reveals the complex volcanic past of the island.
