Four 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.

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Four groups of basaltic cinder cones lie along the major regional N-S-trending Liquine-Ofqui fault zone, which trends parallel to Lake Caburgua (top). The northernmost group of cones lies at the southern end of Lake Caburgua and was the source of lava flows that dammed drainages, forming the lake. The southernmost group, Huelemolle, is the rounded forested area between two rivers at the bottom-center. Two other cone groups lie to the east of Caburgua and Huelemolle. Lake Villarrica is at the lower left, and Colico Lake is at the upper left.

Forested Volcán Relicura, rising to the NW from near the Liucura Bridge, is part of four groups of basaltic cinder cones lying 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. Lava flows from the half dozen cinder cones of the Volcanes de Caburgua blocked drainages, forming elongated Lago Caburgua.

Volcanologists on a field trip during the 2004 Chile IAVCEI conference examine an outcrop of the Caburgua-Huelemolle volcano group. Miocene granodiorites at the base of the roadcut are overlain by postglacial pyroclastic deposits from basaltic cones of the Caburgua-Huelemolle group.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
