Discovered in the year 2000, the Cave of Crystals sits some 300 meters (984 feet) below the surface of the Sierra de Naica Mountain in Chihuahua, Mexico. Home to some of the largest known crystals on the planet, this vast, otherworldly cavern is both beautiful and deadly.
Occupying a U-shaped cavern in the depths of the mountain, the Cave of Crystals measures 30 meters by 10 meters (98 by 33 feet) and is covered top to bottom in enormous cloudy-white selenite gypsum crystals. The tallest of the caves crystals, one of the largest in the world, weighs a whopping 12 tonnes (13.2 tons) and stands 1 meter (3.2 feet) wide and 11.4 meters (37.4 feet) tall thats six times the height of a human!

Conditions in the cavern
While its picturesque interior may look like the perfect photo-op, the Cave of Crystals is closed to the public as the conditions inside are both treacherous and potentially deadly.
With a stable interior temperature of around 58 degrees Celsius (136 degrees Fahrenheit), and humidity levels that reach between 90 and 99 percent, spending any longer than 10 minutes in the cavern unprotected could lead to a build-up of fluid in the lungs and even death.

I don't subscribe to supernatural stuff, but what's happened on this planet, that's given rise to intelligent life ... is the stuff of 'miracles'.
Really it's just mathematics and the laws of physics ... trillions of stars, and even more planets, what we see around us and experience as 'life' is mathematically and physically possible, ergo ... us.
But it literally COULD be the only time 'life' has advanced to the point where we are at in the history of all the universe. So far, for all we KNOW ... that is the case. It's not likely that's true, but we have some sensitive equipment for determining the past existence of other life in the cosmos, and we've found none to date.
Things like seeing people in these magnificent caves just reminds of how incredible and unlikely the human experience has been, contrasted with the vast, cold expanse and vacuum that is 'space'.

want to go even if it were safe.
Spectacular pictures will more than suffice.
