Mount Wrangell

Description

Mount Wrangell is an ice-covered volcano, having last erupted in 1907. It rises due south of another famous Wrangell volcano, Mount Sanford. The summit today is used for research by the U.S. Army, whose buildings are heated by volcanic steam. This same volcanic steam has produced a network of ice caverns in the ice-filled summit crater, a phenomena that is known to exist on only two other North American mountains, Mounts Rainier and Baker, both of Washington state. Wrangell's caldera contains more snow and ice than any other active volcano worldwide, which would cause extensive flooding and mudslides if another eruption were to occur.
