A line of volcanoes extends from
Cerro Cebollar to
Cerro Palpana in south–north direction, of which Cerro de las Cuevas is the youngest volcano.
Potassium-argon dating of the spatter cone on the northeastern flank of the volcano has yielded ages of 3.15±0.15 and 3.36±0.13 million before present.[2]
