Abundant fumaroles in the summit crater of San Cristóbal volcano emit steam in this November 1973 photo. Trees in the foreground were killed by renewed fumarolic activity that began at San Cristóbal in May 1971 after a quiescence of about three centuries. The billowing cloud in the background is an atmospheric cloud.
