Swirling rainbows arch above roaring water as the Snake River cascades 212 feet down a 900 foot wide, horseshoe ridge at Shoshone Falls Park near Twin Falls, Idaho. The widest torrent is Bridal Veil Falls. This spectacle of nature was formed 14,000 years ago during an outburst flooding from a melting glacier. A small fee per car is required to feel the mist as the water thunders 45 feet higher than Niagara Falls.
