From Wikipedia
Mount Moffett is a mountainous stratovolcano that forms the summit of Adak Island of the Aleutian Islands in the U.S. state of Alaska. Its peak reaches 3,924 feet (1,196 m). It is heavily glaciated and is made primarily of high alumina basalt and andesite. It has never had an eruption in recorded history. The southern flank of the mountain is assumed to be its youngest side. In comparison to other Aleutian stratovolcanoes, Moffett is a small vent, characteristic of its mixed composition.
