I love that country you boys were in and if no one explored any of those caves, you don't know what you've missed. I know some folks that have found entire skeletons in some of them in that area,which I personally never looked for or would have bothered had I found any but there are many in that area that have the old fire dumps, out the front, grinding holes inside and out,tons of worked flint and painting on the walls and ceilings. Not to mention all the flood debris you can find (by the way when you do find some of the places with the debris, it'll make you wonder if the camp is high enough up the hill)
