- VolcanoVolcán Mentolat is an active stratovolcano southern Chile located in the central part of Magdalena Island across the Puyuhuapi strait from Puerto Cisnes. The volcano has an ice-filled, 6 km wide caldera. The most recent eruption at Mentolat volcano was around the year 1710. It may have produced a prominent young andesitic lava flow on the western slope of the volcano. An explosive eruption about 7000 years ago produced a wide-spread pumice and scoria layer that extends to the SE.
