[3] Its highest point is the lava dome of Puy de Dôme, located near the middle of the chain, which is 1,465 m (4,806 ft) high.

[4] An outstanding example of plate tectonics in action and continental rifting, the Chaîne des Puys region became a UNESCO World Heritage Site in 2018.

[5] The Chaîne des Puys is located on the Limagne fault, a major part of the European Cenozoic Rift System which formed during the creation of the Alps roughly 35 million years ago.

[6] Before 1750 and the chain's identification as volcanic, the Puys were rumored to be man-made mounds of mining waste or Roman forge furnaces.

These books were the first widely published descriptions of the Chaîne des Puys, and the analysis therein laid the foundation for many of the basic principles of volcanology.
