The summit of Ceboruco volcano provides a panoramic view of the 1870 vent and the San Pedro-Ceboruco graben. The small lava dome at the lower right and the unvegetated lava flow at the lower left were emplaced during the 1870-75 eruption of Ceboruco. The compound Cerro San Pedro lava dome on the horizon directly above the small 1870 dome was constructed within the 7 x 10 km San Pedro caldera. The peak immediately left of Cerro San Pedro is Cerro Tetillas, and the dark-colored area to its left is the Cerro Grande shield volcano.
