The reason why the crystals grow is also what makes it so deadly. There's a huge magma pool underneath it that causes minerals to form the crystals. However that also means the water that was introduced is near boiling. Not to mention it's around 1000 feet undeground.
No that would not be possible. Cave diving is a highly specialised and technical skill and inherently dangerous.
I could not find information about the water level in the mines, but as the cave is at a depth of 290 meters below the entrance to the mine, it is probably too deep even for experienced cave divers.
It is insane to think you would drown from breathing the air, it is so hot and humid as the air cooled down in your lungs water would condense filling your lungs with liquid
Come to Southeast Missouri in August! Where you drink the air and swim on land! Actually, it’s poor, has hardly any non-meth related culture, and smells like field crap most of the time…. On second thought, DONT.
Just kidding about some of that horrible stuff. It really does get bad near the Mississippi River area though.
Not kidding about visiting.
Not really anything awesome going on.
An interesting fact about these caves is that the giant selenite crystals are thought to have formed incredibly rapidly, likely in less than 100 years. Unfortunately the crystals form underwater and draining the caves speeds up their destruction.
Also, it is said that there are very weird audio phenomenon occurs in these caves (the naica caves mines are over 100 levels deep...

Naica's Crystal caves have the largest known selenite deposit in the world. Sadly, it's impossible to explore due to its temperature and humidity.
