The Auvergne Volcanoes - France

I've said it before and I say it again, I like volcanoes. These are 3 wonderful examples of volcanoes cards. All of the are from Auvergne, the land of volcanoes in France. Two were sent by Valérie and the other is an official card. 

Volcanoes, a term which in France is automatically associated with Auvergne in the Massif Central, which was formed 60-million years ago, when the African and European tectonic plates collided. However, the European plate slipped under the African plate.
The thrust weakened it and provoked the appearance of faults lines in the area we today call Massif Central.
Some 25 million years the magma began to rise to the surface in the northern part of the Massif Central. 
There are 450 volcanoes spread in the Chaîne des Puys, Cantal, Monts Dore, Monts d' Artense, Monts du Cantal and Monts du Cézallier (between the Monts Dore and Cantal).
You can discover these volcanoes in the Parc Naturel Régional des Volcans d'Auvergne. - in: https://www.travelfranceonline.com/volcanoes-auvergne-region-central-france/

The Chaîne des Puys is a volcanic alignment of 80 volcanoes that stretches nearly 32 km long and 4 km wide. It is here that the study of volcanoes is born. This natural site includes all forms of volcanism and is a fascinating visual spectacle.
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.

Formed between 95,000 and 8,400 years old, the puys chain is the youngest volcanic ensemble in metropolitan France. It is precisely because these volcanoes are young, that they propose a large variety of forms.
The volcanoes of the Chaîne des Puys have not had time to erode, their forms remained pure and easily interpretable.
