Cerro Overo is located on the lower NE flank of Chiliques volcano, west of the Salar de Aguas Calientes. The 600-m-wide, 50-m-deep maar crater was determined to have a maximum eruption age of 77 ± 7.8 ka based on U-Th/He in zircon from entrained felsic xenoliths (cited in van Alderwerelt, 2017). The 55-m-high La Albóndiga Grande lava dome, about 2 km SW from Cerro Overo, has a similar composition and was considered by van Alderwerelt (2017) to be of similar age from the same magma source. Both erupted through the Atana ignimbrite.
