A blocky lava dome fills Caliente crater at the eastern end of the Santiaguito dome complex in June 1968.  Steam rises from fumaroles along the margins of the roughly 100-m-wide crater in this view from the north.  Periodic ash eruptions accompanied growth of the plug dome.  The Caliente vent is in the oldest part of the Santiaguito dome complex, which began growing in 1922.  It was the source of a major explosive eruption in 1929 that produced large pyroclastic flows.
