Cave of Crystal Giants Superman

Here’s another look at the surreal Cave of the Crystals, a cave connected to the Naica Mine 300-meters below the surface in Naica, Chihuahua, Mexico. The main chamber contains giant selenite crystals, some of the largest natural crystals ever found. The cave’s largest crystal found to date is 12-meters in length, 4-meters in diameter and 55-tons in weight. The cave is extremely hot, with air temperatures reaching up to 58°C with 90% – 99% percent humidity. Without proper protection, people can only endure approximately ten minutes of exposure at a time. Continue reading for more pictures, a full documentary and additional information.

The Cave of Crystals is a horseshoe-shaped cavity in limestone. Its floor is covered with perfectly faceted crystalline blocks. Huge crystal beams jut out from both the blocks and the floor. The caves are accessible today because the mining company’s pumping operations keep them clear of water. If the pumping were stopped, the caves would again be submerged in water. The crystals deteriorate in air, so the Naica Project is attempting to visually document the crystals before they deteriorate further.
