The La Negrillar cone and lava flow complex (also known as Aguas Perdidas) covers a roughly 16 km area along the SW margin of the Atacama basin and was interpreted to be of Holocene age by de Silva and Francis (1991). Gardeweg (1993, pers. comm.), however, did not consider La Negrillar to be of Holocene age, and de Silva (2007 pers. comm.) noted that it was not as youthful looking as the other El Negrillar complex to the north, although it did show leveed lava flows and pristine craters. This basaltic-andesite volcanic field, distinct from El Negrillar (north of Socompa), lies WSW of Socompa volcano between the Sierra San Juan and Sierra Almeida.

The Global Volcanism Program is not aware of any Holocene eruptions from La Negrillar. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the La Negrillar 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.

Aguas Perdidas
The elongated, dark-colored lava flow complex just left of the center of this NASA Landsat image (with north to the top) is La Negrillar. This cone and lava flow complex (also known as Aguas Perdidas) covers a roughly 16 km area along the SW margin of the Atacama basin. The basaltic-andesite volcanic field, distinct from El Negrillar (north of Socompa), lies WSW of Socompa volcano, the source of the lava flows at the far middle-right. Part of the massive debris avalanche from Socompa volcano fills the upper right part of the image.

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.
