40 Strange Cave Discoveries That Are Hard To Be Explained

The Cave Of Crystals

Did we tell you about the life forms found in millions of years old huge block of crystals? What we forgot was about the crystals themselves. These are huge blocks of crystals growing for a very long period of time. Some of them weigh around 55-ton and grow up to a height of 36 feet. That’s quite big. These bulldozer crystals are found in the aptly named Cave of Crystals in Naica, Mexico.

Further, for a human to spend time in these caves is quite difficult as the temperature can rise up to 118 degrees Fahrenheit and humidity to 90 percent. An average human can only survive for around 30 minutes without proper equipment. Want to have a look at some crystals? I suggest finding a place more hospitable towards humans.
