Monday Geology Picture: Another View of Formica Leo Volcanic Crater

Last week I shared a picture of the beautiful and impressive Formica Leo, a volcanic crater located at the Piton de la Fournaise volcano on Réunion Island in the Indian Ocean. Last week’s picture showed the crater from a distance. You can just barely make out some small people in last week’s picture, to give you some sense of scale.
