Around the middle section of the cave tunnels, there's evidence of early humans that once inhabited in the Cave. Humans that's made their home here, performed ceremony rituals, and buried the dead here in certain caverns. Stores of old food, hand made pottery, and tools can be found scattered all over the place. Go into the wrong cavern, and you'll be in among the dried out mummified bodies, and bones, and the permanent lingering dried rotten flesh stink. If you really want to hide from others, this is usually a good place to do it, the predators don't usually care for the smell of dead human. Indians will come back once in a while to these tunnels to perform rituals, and still bury their dead.
