Unidentified man standing next to big hole drilling equipment at the Nevada Test Site. This the IDECO 2500, a diesel electric rig dwarfs normal oil field gear and is capable of drilling holes up to 120 inches in diameter and 6,000 feet deep.
A nuclear explosive and diagnostic canister for a test named "Handley" is lowered down hole at Pahute Mesa in the Northwestern corner of the Nevada Test Site. Pahute Mesa is used for higher-yield tests because of its remoteness. The Handley test was conducted in March, 1970.
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.
View of the north end of Yucca Flat at the Nevada Test Site. Saucer-shaped craters of varying sizes can be seen. These craters are a result of the detonation of explosives during the testing at the Nevada Test Site.
Another view of Sedan Crater formed July 6, 1962, by a test in the Atomic Energy Commission's Plowshare Program to develop peaceful uses for Nuclear explosives. (See also photo #0014 in this collection).
A mushroom cloud rises from the desert floor at the Nevada Test Site. The nuclear test, named DeBaca, was a balloon burst fired in October 1958. (All Nuclear Test Site weapons tests have been underground since July 1962.)
