From Wikipedia

Montagu Island is the largest of the South Sandwich Islands, located in the Scotia Sea off the coast of Antarctica. Almost entirely ice-covered with only sparse rocky outcrops, Montagu consists of a large caldera with a large parasitic cone, Mount Oceanite. Several secondary volcanic cones have formed in the caldera, including Mount Belinda.
