Northern Arizona Volcanoes
Northern Arizona is best known for the Grand Canyon. Less widely known are the hundreds of geologically young volcanoes, at least one of which buried the homes of local residents. San Francisco Mountain, a truncated stratovolcano, was once a much taller structure before it exploded some 400,000 years ago a la Mt. St. Helens.
