Gros Piton, seen here from the summit of the Petit Piton, is the southernmost of the twin lava domes that are the hallmark of the island of St. Lucia.  The 777-m high and 3-km wide dacitic dome was erupted about 260,000 years ago.  Rocks of a small tuff ring are exposed at its base. Photo by Lee Siebert, 1991 (Smithsonian Institution).
