Photo Gallery

Volcán Cay (upper left), is located east of Macá volcano (lower right) and NW of the town of Puerto Aisén. The basaltic and dacitic stratovolcano has an explosion crater that is open to the east, and about a half dozen explosion craters and pyroclastic cones lie along a fissure trending SW of the summit. Another 10 basaltic pyroclastic cones are located along second parallel fissure 5 km to the SE that is part of the major regional Liquiñe-Ofqui fault zone.
