The Sedan Crater, formed by a 104-kiloton thermonuclear detonation in 1962, is a major draw for visitors hoping to land a spot on one of 12 annual tours of the Nevada National Security Site, 100 miles (160 kilometers) northwest of Las Vegas, Nevada, USA, 08 April 2015. The nuclear blast that created Sedan displaced 12 million tons of earth, leaving behind a crater 320 feet (100 meters) deep.
