Lava spines are seen here along the summit ridge of Cerro Quemado, the youngest of a series of lava domes erupted along the margins of Almolonga volcano. The early stages of the Cerro Quemado complex eruptions produced a sequence of lava flows and domes erupted from at least eight vents. During the later stages about 1,150 years ago the summit dome of Cerro Quemado was emplaced following failure of the summit area. An eruption took place from an E-flank vent in 1818.
