Operation Plowshare occurred in what US state?
Sedan (nuclear test) Storax Sedan was a shallow underground nuclear test conducted in Area 10 of Yucca Flat at the Nevada National Security Site on July 6, 1962 as part of Operation Plowshare, a program to investigate the use of nuclear weapons for mining, cratering, and other civilian purposes. The radioactive fallout from the test contaminated more US residents than any other nuclear test. The Sedan Crater is the largest man-made crater in the United States, and is listed on the National Register of Historic Places.
Granite Peak Installation The Granite Peak Installation (GPI) — also known as Granite Peak Range — was a U.S. biological weapons testing facility located on 250 sqmi of Dugway Proving Ground in Utah.
