The Sierra Nevada volcanic complex, located in one of the most inaccessible parts of the Central Andes, covers an area of about 225 sq km astride the Chile-Argentina border. The complex is of partial Holocene age and includes at least 12 volcanic vents with associated lava flows (de Silva and Francis, 1991). Craters up to 400 m in diameter and large andesitic lava flows that extend up to 7 km with well-developed flow ridges are present. The oldest part of the complex, at its eastern end in Argentina, includes two stratovolcanoes, one with a 1-km-wide summit crater.
The Global Volcanism Program is not aware of any Holocene eruptions from Sierra Nevada. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Sierra Nevada 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 large snow-covered massif near the center of this NASA Space Shuttle image (with north to the upper left) is the Sierra Nevada volcanic complex. The complex covers an area of about 225 sq km astride the Chile-Argentina border and includes at least a dozen volcanic vents with associated lava flows. Two large Pleistocene calderas lie south of Sierra Nevada, the 22-km-wide Wheelright caldera (part of which is visible at the lower left) and Escondida at the bottom center, with a lake on its caldera floor.

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.
