Mount Emmons is a post-caldera stratovolcano within the Emmons Lake caldera on the Alaska Peninsula. It is one of three cones constructed within the 7-by-11-mile (11 km × 18 km) caldera, which also contains an elongated crater lake on its southwest side.[1]

The most recent of several caldera-forming eruptions at Emmons Lake occurred more than 10,000 years ago. No historical eruptions have occurred at Emmons Lake.[3]

Mount Emmons is a local name published on a USGS map in 1943.[4]
