Gentry Creek Falls has two distinct and successive 30-40' drops. It's at the end of a 2.5mi hike in Johnson County TN. It's CNF Trail 51 and crosses Gentry Creek 13 times (4 on bridges, the rest quite difficult to stay dry). Info HERE
4/9/2005 - It was way too bright for good waterfall photography, but great hiking weather. There was plenty of water and I splashed and got a bit wet on the last crossing.
