The crater in the center of this photo formed at the base of the 600-m-high headwall scarp of a flank collapse during a Holocene eruption. This view looks W into the horseshoe-shaped crater created during the collapse, with the summit of Iriga in the background. The headwall above the crater is 600 m high.
