Ceboruco, seen here from the west, contains two summit calderas. The rim of the older caldera, which collapsed about 1,000 years ago following eruption of the Jala Pumice, forms the peaks to the left and right of the summit. The thick, light-gray-colored lava flow at the mid left and center part of the photo was produced during the 1870-75 eruption.
