At Rock Island State Park, the widest cataract waterfall in TN works it's way over and around bedrock slabs along a 750 foot segment of the Caney Fork River. This is a segment of the area and falls about 20 feet. This view comes from an observation area from the parking lot, however a trail leads below and one can crawl and splash around, depending on the recent rainfall. This was called Horseshoe Falls in the 1800s.
