Why is the Crystal Cave dangerous?
The place was so humid that a visitor who lingered too long risked having fluids condense inside his or her lungs. That can be fatal. NASA discovered microbial life forms trapped inside one of the crystals that may have laid dormant for up to 50,000 years.
How big is the Cave of Crystals?
The Cave of Crystals is a horseshoe-shaped cavity in limestone rock about 30 feet (10 meters) wide and 90 feet (30 meters) long. Its floor is covered in crystalline, perfectly faceted blocks.
Who owns the Cave of Crystals?
Located in Naica in the municipality of Saucillo, the Naica Mine is a lead, zinc and silver mine operated by Industrias Peñoles, Mexico’s largest lead producer. Caverns discovered during mining operations contain crystals of selenite (gypsum) as large as 4 feet (1.2 m) in diameter and 50 feet (15 m) long.
Which rock has no crystals?
If lava cools almost instantly, the rocks that form are glassy with no individual crystals, like obsidian . There are many other kinds of extrusive igneous rocks . For example, Pele’s hair is long, extremely thin strands of volcanic glass, while pahoehoe is smooth lava that forms shiny, rounded piles.
What is the smallest crystal in the world?
Recently available from River Electronics the FCX-08 package, which is classified as the world’s smallest quartz crystal unit.
Why is it so hot in crystal caves?
The air in the cave has 100% humidity, while the temperature sits at 45 degrees Celsius. Intolerable for humans, but ideal for these astounding crystals . The Naica Mine is located over an intrusion of magma and this is what makes the temperature in the cave so hot .
Why is the Cave of Crystals famous?
For millennia, conditions within the Cave of Crystals (290 m underground) were perfect for the growth of gypsum crystals , allowing them to grow to their massive size. Deep below a mountain near Naica, Mexico, miners searching for fresh ore deposits in 2000 came across an unexpected and awesome sight.
Can you visit the Cave of Crystals?
Unfortunately, tourists are not allowed to visit the Cave of Crystals . The hot and humid conditions make this particular cave a hazardous place to visit , and even scientists need a special permit to enter the cave . You can learn about the various formations there at the online Mineralogy Museum of Mexico.
How old is the Cave of Crystals?
Researchers believe that the largest crystal inside the cave has been growing for over 500,000 years . The crystals have been growing to epic proportions thanks to a prime combination of conditions over the past 10,000 years .

When magma underneath the mountain cooled and the temperature dropped below 58 degrees Celsius, the anhydrite began to dissolve. The anhydrite slowly enriched the waters with sulfate and calcium molecules, which for millions of years have been deposited in the caves in the form of huge selenite gypsum crystals .
What is the tallest cave?
