Formica Leo, Volcanic crater in Sainte-Rose, France
Located at 2218 meters elevation, Formica Leo consists of two overlapping craters with volcanic pebbles ranging from black to red in color.
The crater received its name in 1768 from Joseph Hubert during his expedition through the Enclos Fouqué caldera at Piton de la Fournaise volcano.
French naturalist Jean-Baptiste Bory de Saint-Vincent conducted the first scientific examination of the crater formation in 1801 at Réunion Island.
The crater is accessible through a 2.9-kilometer hiking trail with a 221-meter elevation change, requiring approximately one hour to complete.
The volcanic structure exhibits two distinct craters: a southeastern crater measuring 40 meters wide and 15 meters deep, alongside a smaller northwestern formation.
