Outlaw it's a mixed bag. Here are some pictures not far from my main hunting spot. The flooding picture is an example of the major flooding that pushes up a new batch of artifacts when it floods every so many years. If you google piasa bird you see the history of the big bird like monster Marquette discovered painted by Indians in 1673. The caves are now considered trespassing, I think they were pretty much hunted out in the 50s and 60s I've heard lots of stories of wondrous things being found in them. Pictures are all googled.
