In 2001 Leela Hutchinson became the first American woman to enter the astonishing giant Selenite crystal caves near the village of Naica, Chihuahua in the Sierra Madre Mountains of Mexico. These caves contain what are now known as the largest crystals on Earth ranging in size to 36 feet, and weighing as much as 60 tons and estimated to be 1,000,000 (one million) years old.
Join Leela as she takes you on a journey like none other before into an underground alien world right here on planet Earth. The mysterious giant Selenite crystals of Naica are now known to be the largest crystals discovered. Read why this magical crystal palace has drawn researchers and scientists from around the world to study these giants. This place is considered one of the most hostile environments on earth where a human can die in less than 30 minutes after entering the caverns of 100% humidity and 128 degree [this fooled me, I can boil an egg at this temperature, then I realised that the USA have not gone metric and it is in Fahrenheit instead of 53 degrees C]
