Caves of Naica, Naica, Mexico
Point cloud model of resulting from the laser scanning survey of the Cueva de los Cristales, as a part of the multidisciplinary international “Naica project”.
The mine of Naica is in a semidesertic land about 100 km from Chihuahua, in northern Mexico, and opens on the northern side of the Sierra de Naica.
In 1910 during mining works a small cavity, the Cueva de las Espadas (Cave of the Swords) was discovered at a depth of 120 meters from the entrance. The small cave is a 87 m long corridor completely covered with gypsum crystals, some reaching up to 2 m in length. Few years ago, 170 m below the mining advancement, workers met with another three natural cavities with huge very transparent gypsum crystals. In the Cueva de los Cristales (Cave of the Crystals) some of them reach up to 12 m in length and almost 2 m in diameter.
