Frank,
I'm sure you know a lot more about caves then I do. All I know is they're made of limestone. I would think it wouldn't be that unstable or dangerous. Its been around for hundreds of years if not longer. The limestone caves here, owned by the state are tourist traps. They have tours everyday. I would think if they were dangerous they wouldn't be allowing people to go through them. Your thoughts please.

Clay,
While a large majority of caves are made of Limestone, some are not and some are made up of many types of rocks and rock layers. Yes, some Limestone caves are safe while others are not. The ones that are Tourist traps are inspected regularly by Cave Experts and Engineers to insure that they are stable and safe. Some of these are closed periodically or have sections of the cave closed to either shore-up or remove portions of ceilings, walls, stalactites and/or even stalagmites that develop cracks and/or showing stress. The Limestone caves which have little if any constant dripping of water from the ceilings or water beads on the celings are probably the most stable. However, caves like the one that Brad found which have water flowing overhead, have constant dripping of water from much of the the ceilings and waters beads on much of the celings are not safe! Yes, some of these caves have been around for thousands of years or longer but that doesn't make them safe. Eventually this type of Limestone cave will suffer a cave-in or a major change to it's interior, either due to floods or from the water seeping through the ceilings due to the water flowing over the ceilings. Brad saw such a change to the cave when he, his grandson and his friend crawled back to the crack and tunnel and he saw how the tunnel is now compared to what it was 16 years ago when he last crawled back that far into the cave. He stated to me, that when they saw the change to the tunnel, they immediately turned around and crawled back out of the cave as fast as they could. Many a spelunker and amatuer explorers have died in caves, one of which was Floyd Collins!
