Lake Bolsena formation and topography

Lake Bolsena has a total area of 114m and is nearly circular (at its wides point, it has a diameter of 13 km, at the norrowest 11km) and has a circumference of 43 km and is located at an altitude of 305 meters. Lake Bolsena is surrounded by hills up to 500 meters and has a depth of 151 meters at the deepest point.

As Lake Bolsena was formed by volcanic activity, it seems likely that it could be a crater lake - but the history of formation was different: The „date of birth“ of Lake Bolsena is controversial, but it is probably a good hundred of thousands years back, when this area has emerged from the Latialian Gulf, which does not exist anymore. There were at least four active volcanoes in the mountains around the lake at that time: at Latera, Montefiascone, Bolsena and Capodimonte. In the entire area were at least 94 small craters. You can image the area as a flaming grill without high peaks, which constantly spewed lava and ash.

The period in which this apocalyptic conflagration took part is not known, but it is a fact, that the many craters and the four volcanoes created a cavity, which surface collapsed due to the weight of the Lavas and the volcanic rocks. What was left is a rough rugged valley surrounded by the main volcanoes. After the „geological peace“, torrents from the mountains filled Lake Bolsena with water. Later, there was further volcanic activity, from which the two islands Martana and Bisentina emerged.
