We've got a cavern on our place that runs a couple hundred yards about 25' below ground.
I've posted pics of it here before. Indians definitely lived in it as we find Arrowheads Everytime we go in. Along with several mounds in the pasture above. The idea of living in it has crossed my mind..lol
Like cb said. Constant 65-70 degrees in there year-round.
There is a cave just below my house on the river bluff on our property that is called the Rose Lilly cave. From what I have been told a lady years ago named Rose Lilly lived there. It still has old rusty metal furniture in it. The last time I was down there somebody had their Marijuana curing in it. I made a B line out of there, before I got shot and I know to keep my mouth shut as this has been a few years ago.
