Benton Tennessee cave/cavern @ Cherokee National Forest

[Pullnglide]

I searched and came up with 15 results for Tennessee but none about my question. A few weeks ago I was up in Benton at a campground across from Lake Ocoee. There are waterfalls up there that many people hike to as there are trails everywhere. It was about a 2 mile hike to said waterfall. You come to the first one and you can go up the hill and keep going and the waterfalls continue. We came to a area where there are sheer cliffs and a "pool" that has an overhang of rock and looks to be an overhead environment. Temperature was about 40 degrees so I wasn't going in. Anyone ever been up there and know what I'm talking about. I may take a mask up next time to see what is going on there but carrying scuba is pretty much out of the question.
