A young lava dome on Isla Cook is viewed from the east. This group of andesitic lava domes and pyroclastic cones, known as Volcán Feuguino or Volcán Cook, mark the southernmost Holocene volcanoes of the Andes. They occupy a broad peninsula forming the SE end of Isla Cook and 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.
