The sparsely vegetated ridge across the center of the photo is the distal margin of the Ceboruco 1870 lava flow. The 1.1 km3 lava flow originated from a vent at the western side of the nested summit calderas and traveled 6.5 km down the Arroyo de los Cuates valley to about 900 m elevation. The notch on the right-hand side of the summit ridge is the moat between the nested calderas.
