Boulders litter the foreground in this 1977 view of steaming San Cristóbal (left horizon) and Volcán El Chonco (right horizon). Immediately to the right of El Chonco on its western flank is Loma la Teta, a dacitic lava dome that postdates the collapse. Another small dome, Loma Caparra (barely visible here left of El Chonco and in front of the steaming San Cristóbal volcano in the background) was extruded on the northern flank of El Chonco. The 1105-m-high El Chonco lies at the western end of the San Cristóbal volcanic complex.
