Volcán Puntiagudo

Puntiagudo-Cordon Cenizos

Estratovolcán · Chile · 2493 m

The dramatic summit spire of Volcán Puntiagudo forms one of the most spectacular volcanic peaks of the Andes.  The summit pinnacle, formed as a result of extensive glacial erosion, exposes the volcano's resistant central conduit.  Puntiagudo-Cordón Cenizos volcanic chain lies between Lago Rupanco and Lago Todos Los Santos in the Chilean lake district.  An 18-km-long fissure system with late-Pleistocene to Holocene scoria cones and small stratovolcanoes extends to the NE and was last active in 1850.

Resumen geológico

The Puntiagudo-Cordón Cenizos volcanic chain lies between Lago Rupanco and Lago Todos Los Santos in the Chilean lake district. Volcán Puntiagudo is a late-Pleistocene andesitic stratovolcano with a prominent sharp-peaked summit that results from glacial dissection. An 18-km-long fissure system with more than 40 late-Pleistocene to Holocene basaltic scoria cones and small stratovolcanoes extends to the NE. Lava flows from these centers descend to the NW and SE, in some cases reaching to the shores of the two lakes, forming irregular peninsulas. The only historical eruption occurred in 1850, when ashfall was reported from the Cordón Cenizos chain.
