Nature
Mount Wrangell, in Wrangell–St. Elias National Park and Preserve in southeastern Alaska, is a huge shield volcano and one of the dominant peaks of the Wrangell Mountains. Built over an older volcano, it has an eruptive history reaching back about 750,000 years, with much of its mass formed by lava flows between about 600,000 and 200,000 years ago. Its broad, ice-filled caldera, extensive icefield, fumaroles, cinder cone, and glaciers show a landscape shaped by both volcanism and ice. It is the only volcano in the Wrangell Volcanic Field with historically recorded eruptions, though these were generally small steam and ash events.
