Pago, the flat-topped peak on the center horizon, is a young post-caldera edifice that may have been constructed less than 350 years ago within the 5.5 x 7.5 km Witori caldera. Extensive pyroclastic flows accompanied caldera formation about 3,300 years ago. The low-angled outer slopes of Witori, seen here from the S, consist primarily of pyroclastic flow and airfall deposits produced during a series of five major explosive eruptions from about 5,600 to 1,200 years ago.
