Photo Gallery

The St. Michael volcanic field consists of more than 55 cones and craters occupying Stuart Island (upper left), St. Michael Island (forming the apparent peninsula at left-center, and areas inland. Broad low shield volcanoes underlie the younger cones, and maar volcanoes are located at the SW part of the volcanic field, which covers >3000 sq km. Light-colored young lava flows can be seen at the lower right originating from "The Sisters" area. Native tradition says that a village was submerged by lava three times.
