In Focus has posted a bunch of large photos of nuclear bomb tests conducting during this century.

While we often think of nuclear bombs as mushroom clouds rising high above the earth, it’s rare that we see images of the results on the Earth’s crust. In the photo above, a 100 kiloton bomb was detonated beneath 635 feet of desert sand and this 320-foot deep by 1280-foot in diameter hole was dug into the ground. Crazy right?
