That’s what I was thinking & then they took off air mask for a minute. Man, not this kid. I love selenite & have plenty, but death by whatever lung disease doesn’t sound like any kind of good time.

I thought the whole thing was that it was super high humidity and temp well above body temp such that the water in the air condenses in your lungs and you drown.

The cave is an extremely hostile environment for humans, with temperatures reaching 50°C (122°F) and 90% humidity. Access is limited and requires special cooling suits and limited time frames due to the dangerous conditions.

I saw on a science show, but google is my friend

I'm sure that's correct. I was just thinking of particulates because of how selenite fractures. I've gotten a selenite splinter before, so my first thought was just about what could be in the air.

Oh, that would also suck!
