Sedan Crater was formed when a 100 kiloton (KT) explosive was fired at the Nevada Test Site on July 6, 1962, displacing 12 million tons of earth. The crater is 320 feet deep and 1280 feet in diameter.
"Sedan" was part of the Plowshare Program at the Nevada Test Site. It was fired on July 6, 1962. Heavier particles began falling back to earth as the main cloud continued to rise. The base surge of dust began to roll along the desert floor.
