The rounded Terre Blanche lava dome (center) was constructed within the 3.5 x 5 km wide Qualibou caldera.  The dome is seen here from the summit of Petit Piton, a pre-caldera lava dome, with the skyline ridge forming the NE caldera wall.  Andesitic lava flows and breccias are exposed in the caldera wall.  The 450-m-high Terre Blanche dome is one of 3 dacitic lava domes that grew following formation of the caldera about 39,000 years ago. Photo by Lee Siebert, 1991 (Smithsonian Institution).
