Photo Gallery

Volcán Mentolat is an ice-filled 6-km-wide caldera in the central part of Magdalena Island, across the Puyuhuapi strait from the town of Puerto Cisnes. A young-looking andesitic lava flow on the west side of the volcano may be its most recent product. Historical reports describe an eruption at the beginning of the 18th century that could refer to this lava flow.
