The walls of two nested summit calderas are seen here in an aerial view of Ceboruco from the NE, with the road to the summit. The formation of the 3.7-km-wide outer caldera was associated with eruption of the 5 km3 Jala Pumice and the Marquesado pyroclastic flow about 1,000 years ago. The Jala Pumice covers broad areas to the north and east. Photo by Jim Luhr, 1980 (Smithsonian Institution).
