Puyehue Cordon Caulle volcano, Chile

The Puyehue-Cordon Caulle volcanic complex forms the horizon in this view looking north across the Rio Gol Gol valley from the Antillanca volcano group.

Flat-topped 2236-m-high Puyehue volcano (right) is a late-Pleistocene to Holocene basaltic-to-rhyolitic stratovolcano constructed above a 5-km-wide caldera and capped by a 2.4-km-wide summit caldera.

Historical eruptions originally attributed to Puyehue are now known to be from the Cordon Caulle rift zone, the long snow-covered ridge that extends across the photo to the left of Puyehue.

The Puyehue-Cordon Caulle volcanic complex (PCCVC) is a large NW-SE-trending late-Pleistocene to Holocene basaltic-to-rhyolitic transverse volcanic chain SE of Lago Ranco.

The 1799-m-high Pleistocene Cordillera Nevada caldera lies at the NW end, separated from Puyehue stratovolcano at the SE end by the Cordon Caulle fissure complex.

The Pleistocene Mencheca volcano with Holocene flank cones lies NE of Puyehue.

The basaltic-to-rhyolitic Puyehue volcano is the most geochemically diverse of the PCCVC.

The flat-topped, 2236-m-high Puyehue volcano was constructed above a 5-km-wide caldera and is capped by a 2.4-km-wide summit caldera of Holocene age.

Lava flows and domes of mostly rhyolitic composition are found on the eastern flank of Puyehue.

Historical eruptions originally attributed to Puyehue, including major eruptions in 1921-22 and 1960, are now known to be from the Cordon Caulle rift zone.

The Cordon Caulle geothermal area, occupying a 6 x 13 km wide volcano-tectonic depression, is the largest active geothermal area of the southern Andes volcanic zone.
