"It is pitch black. You are likely to be eaten by a grue."
It was discovered back in 1804 by a teenager named Bernard Weyer. One of his animal traps went missing and, reluctant to let it go, he followed it down a hole. There underneath the ground he found the pre-Cambrian limestone melting like hot candle wax across the thousands of years.
It's the sort of landscape through which a larval geek may easily imagine carrying a brass lantern and elvish sword of great antiquity in search of lost treasures.
Even after tourists had visited the caverns for nearly 200 years. a new set of caves was uncovered by a search and rescue dog named Rosie in 2004. They stretch out more than 3 miles further than anyone had ever expected.
This fact makes me smile every time I think about it. It's good to know that there are still things left to be found out there in the world.
Undiscovered caves, full of treasures, sasquatch and lake monsters.
