The truncated summit of Pinatubo is seen from the E at Clark Air Base in 1992. The light brown, unvegetated peak at the left center is the southern rim of the new caldera and summit of Pinatubo. The northern caldera rim lies about 2/3 of the distance between the summit and the unvegetated peak to the right, which is a relict of a caldera rim of ancestral Pinatubo volcano.
