The four major domes of the Santiaguito complex are seen here from the summit of Santa María in 1980. Caliente is degassing to the left, with La Mitad and El Monje in the center, and El Brujo to the right. The dacite dome complex stretches about 3 km in a roughly E-W direction. Lava flows and lahar channels extend down drainages from the dome complex to the south. Photo by Bill Rose, 1980 (Michigan Technological University).
