Volcano Type: Complex volcano
Volcano Status: Holocene
Last Known Eruption: Unknown

Cerro Bayo is a complex volcano of partial Holocene age located along the Chile-Argentina border. An older center to the south contains a poorly preserved, 800-m-wide crater. A younger northern center along the national border has a well-preserved 400-m-wide crater and produced lava flows to the north and NE. The 5401-m-high summit of the Cerro Bayo complex, located west of the border in Chile, is the source of two viscous dacitic lava flows that traveled to the north and represent the most recent activity of the complex.

Volcano Type: Stratovolcano
Volcano Status: Holocene
Last Known Eruption: Unknown
Summit Elevation: 5697 m 18,691 feet

The NNW-trending edifice of 5697-m-high Lastarria volcano along the Chile-Argentina border contains five nested summit craters. The youngest feature is a lava dome that overlaps the northern crater rim. The large andesitic-dacitic Negriales lava field on the western flanks was erupted from a single SW-flank vent. A large debris-avalanche deposit is found on the SE flank. Recent pyroclastic-flow deposits form an extensive apron below the northern flanks of the volcano.

Volcano Type: Scoria cones
Volcano Status: Holocene
Last Known Eruption: Unknown
Summit Elevation: 4000 m 13,123 feet
Latitude: 26.08°S * 26°5’0″S
Longitude: 67.50°W 67°30’0″W
The Antofagasta de la Sierra volcanic field contains some of the youngest volcanic vents of the Argentinian Puna region. The volcanic field is located SW of Beltran volcano and between the Salar de Antofalla on the west and the massive Cerro Galán caldera on the east.
The Antofagasta de la Sierra volcanic field contains several very youthful looking basaltic-andesite scoria cones and fresh-looking lava flows, which may only be a few thousand years old. A concentration of scoria cones and lava flows east of the NE-SW-trending Salar de Antofalla, known as the Salar de Antofalla volcanic field, also have a youthful appearance, although precise ages are not known.

Volcano Type: Stratovolcano
Volcano Status: Holocene
Last Known Eruption: Unknown
Summit Elevation: 5740 m 18,832 feet
Latitude: 26.62°S 26°37’0″S
Longitude: 68.15°W 68°9’0″W
This symmetrical Argentinian stratovolcano is the source of well-preserved lava flows of Holocene age from summit and flank vents. Cerro Peinado is one of the youngest volcanoes in the region. The upper part of the 5740-m-high cone is blanketed by pyroclastic material.
Two possible pyroclastic-flow lobes extend to the NW and north. Cerro Peinado contains an apron of pristine lava flows extending to 6 km. These were erupted from the main cone and from vents on the flank, including a prominent ESE-flank vent. Cerro Peinado is surrounded by small fields of cinder cones, maars, and pristine lava flows, located along N-S-trending faults, which are related to the Salar de Antofalla volcanic field.
