The irregular hummocky terrain extending to the south toward the Pacific coastal plain is part of a massive debris avalanche deposit that originated from flank collapse of Volcán Barú. This view is from Cerro Pando, a lava dome to the west. At least two flank failure events have occurred, producing voluminous debris avalanche deposits that form a broad deposit reaching beyond the Pan-American highway to the Pacific coastal plain.
