Nevado de Incahuasi is a complex volcanic massif that straddles the Chile-Argentina border ENE of Nevados Ojos del Salado volcano. Two stratovolcanoes occupy a compound 3.5-km-wide caldera, and Pleistocene lava domes are located on the W and SW flanks of the 6638-m-high volcano. The youngest stratovolcano is capped by a 1-km-wide crater, and dacitic lava flows radiate down the volcano's flanks. The fresh-looking morphology of the youngest products suggest a Holocene (González-Ferrán, 1995) or possible Holocene (de Silva 2007, pers. comm.) age. A dacitic lava dome partially fills an arcuate crater on the eastern flank of Incahuasi (which means "House of the Inca" in Quechua). Four pyroclastic cones are located 7 km to NE and produced basaltic-andesite lava flows that cover an area of 10 sq km.
The Global Volcanism Program is not aware of any Holocene eruptions from Nevado de Incahuasi. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Nevado de Incahuasi 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.

|Snow and ice drapes the western flank of Nevado Incahuasi along the Chile/Argentina border, as seen from Paso las Lozas at 5100 m. Nevado de Incahuasi is a complex volcanic massif located ENE of Nevados Ojos del Salado volcano. Two stratovolcanoes occupy a compound 3.5 -km-wide caldera. Pleistocene lava domes are located on the west and SW flanks of the 6621-m-high Nevado de Incahuasi, one of the world's highest volcanoes.

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.
