Sharp-topped Santa María is one of Guatemala's most active volcanoes.  The steaming Santiaguito lava dome was constructed beginning in 1922 at the base of a large crater excavated in the SW flank of Santa María during a major explosive eruption in 1902.  Light-colored sediment fills the moat to the left of the dome, between it and the 1902 crater wall.  Lava flows accompanying growth of the dome descend towards the lower right.  The lower peak behind and to the left of Santa María is Cerro Quemado, a lava-dome complex of the Almolonga caldera. Photo by Bill Rose, 1980 (Michigan Technological University).
