Mount Emmons

Mount Emmons is a stratovolcano located within the Emmons Lake caldera on the Alaska Peninsula. The volcano rises approximately 1,436 meters (4,711 feet) and features three distinct cones with a crater lake situated on its southwestern slope.

The volcano experienced its last significant eruption more than 10,000 years ago, which contributed to the formation of the Emmons Lake caldera. Since then, it has remained dormant without recorded eruptive activity.

The Alaska Volcano Observatory conducts regular monitoring of Mount Emmons to study volcanic patterns and geological changes in the Alaska Peninsula.

The location sits approximately 40 kilometers (25 miles) east of Cold Bay and 34 kilometers (21 miles) northeast of King Cove, which serve as the nearest communities. These settlements are the main jumping-off points for access to this remote area.

The caldera surrounding the volcano spans approximately 18 by 11 kilometers and contains a total of three separate stratovolcanoes within its boundaries. The geological formation shows distinctive breaches on both its northern and southern sides.
