The Chaîne des Puys, prominent in the history of volcanology, form a N-S-trending chain of basaltic and trachytic cinder cones, basaltic maars, and trachytic lava domes in France's Massif Central that has been active into the Holocene. Construction of the present-day Chaîne des Puys began about 70,000 years before present (BP), and was largely completed by the beginning of the Holocene. Holocene eruptions constructed lava domes such as the Puy de Dôme, whose growth was accompanied by pyroclastic flows, cinder cones that fed lengthy lava flows, and maars. The latest well-documented activity took place about 6000 years BP near Besse-en-Chandesse and included the powerful explosions that formed the Lac Pavin maar. The dating of younger tephras has not yet been confirmed, and reports of historical eruptions as late as 1000 years BP have been discredited.
