A group of andesitic, columnar-jointed lava domes and pyroclastic cones up to 150 m high on Isla Cook mark the southernmost Holocene volcanoes of the Andes. The volcanoes, known as Volcán Cook or Volcán Fueguino, occupy a broad peninsula forming the SE end of the island. One of the cones, S of Bahía del Volcán, contains a 150-m-wide crater with a small lake. The lava domes and pyroclastic cones, possibly emplaced along N-S-trending faults, are unaffected by glacial erosion that scoured the underlying plutonic rocks. Passing navigators observed possible eruptive activity in the direction of Cook in 1712 and the eruption of incandescent ejecta in 1820.
