Background4 groups of basaltic cinder cones lie east of Lago Villarrica and NE of Villarrica volcano: The northernmost and southernmost groups, the Volcanes de Caburgua and Volcán Huelemolle, respectively, lie along the major regional Liquine-Ofqui fault zone. Volcanes de Caburgua lies at the south end of Lago Caburgua and consists of six early Holocene basaltic cinder cones. Lava flows from these cones contributed to blockage of river drainages that formed the lake. The southernmost group, Volcán Huelemolle, consists of three early Holocene basaltic cinder cones between the Liucura and Pucón (or Minetué) rivers. The two other cone groups, Volcán Redondo and Pichares, lie to the east of Caburgua and Huelemolle. Stratigraphic evidence indicates that these basaltic cone groups were active between about 6000 and 8000 years ago.
