Crystal Cave
We’ve mentioned several crystals in caves in this list as they continue to be such a fascinating thing. There’s one variety of crystals that are so long, they’re capable of rivaling the telephone poles we see today. These long crystals can be found in the Cave of Crystals in Mexico and are capable of growing up to 36 feet and weighing as heavy as 55 tons. However, an average person can’t venture through this cave as it can reach as high as 118 degrees Fahrenheit.
