The solitary Cerro Overo maar is located on the lower NE flank of Chiliques volcano, west of the Salar de Aguas Calientes. The youthful morphology of the maar suggests a possible Holocene age. The 600-m-wide, 80-m-deep mafic maar produced the least silicic youthful volcanic rocks found in this part of the central Andes.
