Le Puy de Côme (department of Puy de Dôme, Auvergne-Rhône-Alpes). The slopes of this ancient strombolian volcano are covered with well-aligned wood plantations, which make it recognize from afar. It is an almost perfect basaltic cone culminating at 1,253 meters above sea level. It has two craters nested with practically the same axis, sign of two eruptive phases. Its volume is about 190 million cubic meters. Its lava flows, called Cheires, are the most important of the entire volcanic chain. Its lava descended to the site of the present city of Pontgibaud and the river Sioule, tributary of the left bank of the Allier, forcing it to create a new bed. As the flows of the Como Puy are superimposed over the successive eruptions, they reach a thickness of 130 meters measured during a survey carried out at 1.5 kilometers of the volcano.
