The Chaîne des Puys (]) is a north-south oriented chain of cinder cones, lava domes, and maars in the Massif Central of France. The chain is about 40 km (25 mi) long, and the identified volcanic features include 48 cinder cones, eight lava domes, and 15 maars and explosion craters. Its highest point is the lava dome of Puy de Dôme, located near the middle of the chain, which is high. The name of the range comes from a French term, puy, that refers to a volcanic mountain with a rounded profile. A date of 4040 BCE is usually given for the last eruption of a Chaîne des Puys volcano.
