Steam pours from vigorous fumaroles near the summit of Volcán Ollagüe.  This massive 5868-m-high stratovolcano is capped by a large dacitic lava dome.  Collapse of the volcano produced a massive Pleistocene debris-avalanche deposit that extends to the west.  Active sulfur mines on the upper western and southern flanks are reached by a road that climbs to about 5500 m elevation.  Only increased fumarolic activity has been recorded at Ollagüe during historical time. Photo by Oscar González-Ferrán (University of Chile).
