Volcán Macá rises to 2960 m NW of Puerto Aisén and is the highest volcano between Lanín and Lautaro. This glacier-covered, basaltic-to-dacitic stratovolcano lies within a caldera and contains a summit lava dome. Five flank cinder cones and lava domes lie along a NE-trending fissure that extends 15 km from the summit. The volcano lies along the regional Liquiñe-Ofqui fault zone, and tephra layer of late-Holocene age was documented.
