In this photo is a mushroom cloud from atomic testing in the Southern Nevada Desert occurring exactly 62 years ago in 1957. Between 1951 and 1992, the U.S. government conducted a total of 1,021 nuclear tests here. Out of these tests 100 were atmospheric, and 921 were underground. A similar test was done in Churchill County as well, referred to as Project Shoal. The nuclear device was detonated on October 26, 1963, 1,200 feet under ground. Project Shoal was one of three nuclear test conducted outside of the Nevada Test Site. Churchill County was chosen because they wanted to know the results of a nuclear underground explosion on fault lines.
