The Sedan nuclear crater is located at the Nevada Test Site, about 90 miles north of Las Vegas. It is the result of the Sedan nuclear test, an underground nuclear test carried out on 6 July 1962 as part of the Plowshare Program, established in June 1957 to explore peaceful applications for controlled nuclear detonations. The idea was that a nuclear explosion could easily excavate a large area, facilitating the building of canals and roads, improving mining techniques, or simply moving a large amount of rock and soil. The intensity and distribution of radiation, however, proved too great, and the program was abandoned. Operation Plowshare resulted in 27 thermonuclear detonations. Only four events were intended to produce craters, among which Sedan was by far the largest.
