The San Salvador volcano is located in central El Salvador. The prominence currently consists of two masses: one called El Picacho at 1960 m; and the other known as El Boquerón at 1839 m, which includes a 1.5 km wide crater. Other inactive craters are located around these elevations. In the interior of El Boquerón there was a lagoon of unknown origin, which was extinguished by boiling due to eruptive phenomena during the San Salvador earthquake of 1917. Today, a small elevation can be seen at the bottom of the Boquerón crater. - 1977

One of the most magnificent sights in the Sahara: the large «Natron Hole» in Tibesti (Chad). This former crater has a diameter of 6 kilometres and a depth of 600 metres. The Toubou, nomads of the Tibesti, extract the sodium bicarbonate there, which is intended for the camels, and load it onto the donkeys, the only animals that can walk the very narrow and very steep path. – Tibesti - Chad - 1967

The Saharan atmosphere is so strange, so out of keeping with the one that has shaped our minds, that it is not difficult to forget what we know about geography when we come into contact with it. In reality, we are only in front of another aspect of the planet and it is in the presence of a dormant volcano, and not a dead one like the one shown here, that we find our sense of the Universal. The "Natron hole" is, as its name suggests, a salt reserve in a country where salt is scarce. The Tubu who exploit it reserve it for their animals. - Chad - 1967
