1951: The first U.S. underground atom bomb test is detonated at Frenchman Flat, a 123-square-mile dry lake bed at the Nevada Test Site. The 1.2 kiloton explosion, codenamed "Uncle" as the last of a series of seven tests termed Operation Buster-Jangle, took place 17 feet underground and left behind a hole 53-feet deep and 260-feet wide.
