According to the National Geographic magazine website, in 2000, scientists discovered a giant crystal hole in the depths of 1,000 feet (about 304 meters) in the Nika Mountains in the Chihuahua Desert in Mexico, which is another natural wonder. In 2008 and 2009, scientists returned to the giant crystal cave in Mexico, and in the expedition, they unveiled many biological mysteries and discovered an "ice palace" with four walls covered with rare crystals.

In December 2009, about 500 feet (about 150 meters) underground, the newly discovered "Ice Palace" floor on the crystal cave top and the crystal "cauliflower" grown on the roof.

3. Cool "Ice House"
In 2009, an expedition in the Crystal Cave shivered in the cubic "IceCube". The so-called "ice house" is a tent that is cooled by air and surrounded by plastic to complete the two-hour task in an extremely humid and stuffy crystal hole. Although the crystal cave is hot and humid, the temperature of this portable shelter will never drop to a very low level, ensuring that the expedition team's overheated body returns to a safe level.
4. "Sword of King Arthur"
The so-called "Sword of Arthur" crystal protrudes from the ground of the crystal cave. According to John Lakovan, a mineralogist at the University of Miami in the United States, this bladed icicle exhibits a diamond-like shape that is not visible in any giant crystals outside the crystal cave.
5. Sparkling crystals
In 2009, a rare crystal structure like thin optical fibers illuminates the ground of the newly discovered "Ice Palace" cave.

6. The hotbed of the virus
In December 2009, three scientists, Penelope Boston, Michael Spilder, and Danielle Winget, collected samples from a puddle in the Crystal Cave. Afterwards, laboratory analysis showed that every drop of water in this ice cave contained up to 200 million viruses.
