The dramatic Delta Lávico flow forms a peninsula on the SE flank of Volcán Bárcena at the southern end of San Benedicto Island.  The tuff cone and lava flow were formed during the 1952-53 eruption.  The Bárcena tuff cone now marks the high point of the island.  The flat-topped cone at the right is Cráter Herrera, a trachytic lava dome capped by a smooth-floored crater.  Another lava dome, Roca Challenger, forms the northern tip of the island beyond Cráter Herrera. Photo by Hugo Delgado-Granados, 1993 (Universidad Nacional Autónoma de México).
