Roaring Fork may seem like a misnomer for this mountain stream in Great Smoky Mountains National Park. During dry spells, it"s a gentle brook. But Roaring Fork descends 2,500 feet over just 2 miles—a steep drop down Mount Le Conte. When heavy rains swell the stream, Roaring Fork transforms into a whitewater rush, with the sound of the surging water echoing off the sandstone walls of the mountain.
