Descabezado Grande

Type
Stratovolcano
Elevation
3953m
Last eruption
1933
Volcán Descabezado Grande, seen here from the west, is a late-Pleistocene to Holocene stratovolcano with a 1.4-km-wide ice-filled summit crater. The Holocene Alto de las Mulas fissure on the lower NW flank (out of view to the left) produced young rhyodacitic lava flows. A lateral crater formed on the upper NNE flank in 1932, shortly after the end of the major 1932 eruption from nearby Quizapú volcano. This was the site of the only historical eruption of Descabezado Grande.

From Wikipedia

Descabezado Grande is a stratovolcano located in the Maule Region of central Chile. It is capped by a 1.4-kilometre-wide (0.9 mi) ice-filled caldera and named for its flat-topped form, as descabezado means "headless" in Spanish. A smaller crater about 500 metres (1,600 ft) wide is found in the northeast part of the caldera, and it has active fumaroles.
