Two intersecting volcanic chains, the Cordón de Puntas Negras and Cordón Chalviri, trend roughly SE from Chiliques volcano to Volcán Puntas Negras stratovolcano and SW from there to Cerro Tuyajto, respectively. The chain of small cones, lava domes, lava flows, and maars covers an area of about 500 sq km and contains at least 25 different vents. The Cordón de Puntas Negras is situated along the southern margin of the 35 x 70 km Pliocene La Pacana caldera. The pristine morphology of many of the volcanic features indicates a Holocene (de Silva and Francis, 1991) or historical (González-Ferrán, 1995) age. Small cones such as Cerros Cenizas, Aguas Calientes, Laguna Escondida, and Chinchilla have well-preserved summit craters and produced short lava flows. A distinct maar-type vent is present, as well as a 13 sq km silicic lava flow and dome complex. A volcanic center immediately SE of Cerro Laguna Escondida appears to be the youngest vent of the complex.

The Global Volcanism Program is not aware of any Holocene eruptions from Cordon de Puntas Negras. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Cordon de Puntas Negras page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

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.

The Cordón de Puntas Negras, a NW-SE-trending chain of small cones, lava domes, and lava flows, extends from SE of Cerro Chiliques to the Volcán Puntas Negras stratovolcano. This view of the southern end of the chain shows multiple vents that fed pristine-looking lava flows with prominent flow levees. The Cordón de Puntas Negras chain is situated along the southern margin of the 35 x 70 km Pliocene La Pacana caldera.

Cerro Overo maar in the foreground was formed by phreatomagmatic explosions. A thin, roughly 1.5-m-thick, dark-colored ejecta blanket surrounds the 600-m-wide, 80-m-deep maar. The maar is located on the lower NE flank of Volcán Chiliques and was erupted along a regional fault through basement ignimbrites of Pliocene age from the La Pacana caldera. On the horizon to the right is the east side of Tumisa and the dome "Negro de Barriales." On the left is the Lejia stratovolcano and caldera. Laguna Agua Caliente is at the right-center.

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.
