1: caves are dangerous as fuck. real easy to die in one if you don't know what you're doing.
2: caves are fragile places. formations that have taken 100k years to form are destroy just by a touch. and everyone that enters the cave is bring in new outside contaminants
3:publicly posting the location of a cave is a good way to turn into a party spot for teenagers and druggies. so instead of a natural cave, you have a hole in the ground full of beer cans and human waste.
4:did I mention that most caves are dangerous? you don't want to enter most caves simply because they're so unstable. a cave in shale or clay isn't like a cave in limestone and granite. the composition of a cave can change as you move through it. you do know how to watch for those changes, right anon?>how do I find caves
by learning about them. go to your library and see what books on caves and geology they have.
You'll learn the terms you need to search to find what you're looking for.
hopefully by the time you find some caves, you'll know enough to do it safely. or safer anyway.
