Flat Rock

Hello everyone. I have been researching nude/clothes optional spots in the SW Missouri, NW Arkansas area and ran across a article on Flat Rock on the White River in Madison Co. Arkansas. It's SE of Fatetteville down past Elkins off of Hwy 16. I was wondering if anyone has been there or has heard about it? I would go down and check it out but I'm not sure of the best way to get in there. Any information would be appreciated.
Thanks,
Trace
