Superman’s Fortress of Solitude :)
Crystal Cave of the Giants - Naica, Saucillo Municipality, Chihuahua, Mexico
What do you get when you take a super-saturated solution of Gypsum, apply even heat from a magma chamber, let it sit for 500,000 years, and then pump out all the water?
A geode full of spectacular crystals as tall as pine trees, and in some cases greater in circumference, they are a translucent gold and silver in color and come in many incredible forms and shapes. Found deep inside a mine in southern Chihuahua Mexico, these crystals were formed in a natural cave totally enclosed in bedrock. The Crystal Cave of the Giants was discovered within the same limestone body that hosts the silver-zinc-lead ore bodies exploited by the mine and it was probably dissolved by the same hydrothermal fluids that deposited the metals with the gypsum being crystallized during the waning stages of mineralization.
The caves look like Superman's ethereal Arctic lair.
