Yes, you read that correctly: volcanoes in France. Puy de Dôme is an active volcanic dome in the Masif Central region, close to the middle of the country. It's less than 11,000 years old, a newborn in geological terms. Contributor Astropote used a drone and four spotters to fly over the crater of the great dome, which is about 200 meters (650 ft) across and 90 meters (300 ft.) deep. Puy de Dôme is now one of the major tourist destinations in south-central France.
