An ash column rises above Santiaguito lava dome in June 1976 nearly to the height of Santa María's summit. Santiaguito lava-dome complex was constructed within a large explosion crater that cut the SW flank of the volcano during the major 1902 explosive eruption. The crater, seen in profile here, extends from just below the 3772-m-high summit to 2200 m elevation, below the bottom of the photo. Santiaguito's summit is at about 2500 m elevation.
