I was watching something the other day where these guys went through this tiny little hole in the ground. It turned into a massive cavern hundreds of feet deep then they followed the cave as it narrowed, by the end of, he had taken off most of his gear and was straining to pull himself through crevices that he really didn’t fit through. One slight mistake or a shift in some rocks and you’re done. If the guy he was with was a little bit bigger and couldn’t get through the crevice he couldn’t even get in to save his ass. Yeah no thanks.

Underwater spelunking is significantly more dangerous because you have a very limited oxygen supply and it’s very easy to get confused about which way is up. And every time you get near a surface you end up having zero visibility. Everywhere you go your equipment’s getting stuck on things.

To be honest either one of those can fuck right off, we don’t even need a contest.
