Twin Falls became the center of national attention in September 1974, when daredevil Evel Knievel attempted to jump the Snake River Canyon in a specially modified rocket cycle. Watched by millions on closed-circuit television on a Sunday afternoon, the attempt ultimately failed due to high winds and a premature deployment of Knievel's parachute. The launch ramp's foundation lies on private land on the canyon's south rim. Less than two miles west (3 km) of Shoshone Falls, it is still visible ().
