The irregular, hummocky terrain extending to the SW toward the Pacific coastal plain is part of a massive debris-avalanche deposit that originated from edifice collapse of Volcán Tisingal. This view is from Cerro Pando, a satellitic lava dome south of Volcán Colorado. Both volcanoes of the Barú-Colorado complex underwent edifice failure, producing voluminous debris-avalanche deposits that form a broad blanket reaching beyond the Panamerican highway to the Pacific coastal plain.
