Chaîne des Puys - faille de Limagne
Geological exploration of the Auvergne-Rhône-Alpes volcanic chain
Spanning a rhythmic skyline of roughly eighty volcanoes, the Chaîne des Puys - faille de Limagne represents a premier site for studying continental rifting and volcanic landforms. This protected monument offers a clear view into the interplay between the ancient mountain basement, the massive Limagne fault, and the resulting volcanic edifices that define the regional identity of the Auvergne-Rhône-Alpes area.
