The SW side of Volcán Cacao, located at the SE end of the Orosí volcanic massif, is cut by an arcuate depression created during a massive slope failure in which the summit of the volcano was removed. The vertical light-colored stripes on the upper edifice are rockslide scars. The latest eruptive activity at the Orosí complex consisted of post-collapse lava domes and flows from Cerro Cacao.
