Mount Adagdak is a Pleistocene age stratovolcano on the northernmost extremity of Adak Island in the Aleutian Islands, Alaska. Located about 1180miles from Anchorage, the mountain is located about 1.41NaN1 south of Cape Adagdak, for which it was named in 1948 by the United States Geological Survey.
The volcano is made up of rock from three different periods of activity. The youngest rock was argon dated to between 205,000 - 215,000 years old.[2]
John Hunter of Quicklaunch has twice proposed the use of Mount Adagdak's western slope as the emplacement site for a light-gas gun to launch small payloads into orbit for use at ISS.[3]
