Puntiagudo-Cordón Cenizos, Stratovolcano in Llanquihue Province, Chile.

Puntiagudo-Cordón Cenizos is an andesite stratovolcano located between Rupanco Lake and Todos los Santos Lake in Llanquihue Province. Its distinctive sharp peak rises to 2,493 meters and was sculpted by glacial erosion over time.

The first recorded ascent took place in 1937 when Swiss mountaineer Hermann Hess and Chilean Rodolfo Roth reached the summit via Lake Todos los Santos. A major earthquake in 1960 subsequently altered the volcano's summit profile.

Local mountaineers consider this volcano among the most demanding peaks to climb in southern Chile, requiring extensive preparation and technical expertise.

Access is by two trails: one from Puntiagudo Valley and another from the southeast shore of Rupanco Lake, the latter suited only to hikers. The summit is counted among the hardest in Los Lagos, and the 1937 first ascent ended in Rodolfo Roth's fatal 200 m fall on the east glacier. The volcano is not monitored by Sernageomin.

Locals say the Puntiagudo lost part of its sharp point in the 1960 earthquake, so the summit was more pointed before. The volcano is also called Cerro Cenizas, and its name comes from the sharp form left by glacial dissection.
