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.
