Published September 2, 2007
Arcing southwestward from Alaska like the tail of a kite, the Aleutian Islands are a string of active and dormant volcanoes fed by magma created by the collision of the Pacific Plate with the North American Plate. In the northeast part of the range, a cluster of summits known as the Islands of the Four Mountains is home to Cleveland Volcano, one of the Aleutians’ most frequently active volcanoes.
