By the time of this June 7, 1960 photo, the steaming lava dome had risen to the height of the crater rim of Colima volcano. After about a quarter century of quiescence, the dome had begun rising again in May 1957 from a depth about 50 m below the notch in the northern crater rim (center) known as La Gran Vena. Dome growth continued, and in 1961 lava began spilling out of the crater through this notch and down the northern flank.
