Mount Adagdak

Mount Adagdak is a stratovolcano on Adak Island in the Aleutian Islands, rising approximately 641 meters (2,100 feet) above sea level. The mountain displays multiple craters and shows evidence of different volcanic activity phases across its slopes and summit area.

The peak was officially named by the United States Geological Survey in 1948, taking its name from nearby Cape Adagdak. Scientific studies later revealed that the youngest volcanic rocks date between 205,000 and 215,000 years ago, marking the mountain's most recent activity.

The volcanic formation represents a significant geological landmark in the Aleutian Range, ranking as the 71st most prominent peak among 297 mountains.

The location is remote and difficult to reach, requiring careful planning and appropriate gear for harsh weather conditions. Access to Adak Island involves significant travel time from major population centers in Alaska.

The western slope of Mount Adagdak has been identified as a potential location for a light-gas gun to launch small payloads to the International Space Station.
