US nuclear bomb test site
A place with hundreds of craters from nuclear bomb tests of various strength: 37.177 -116.0462. The coordinates point to a large crater which was created by the test explosion Sedan (Video) in 1962. If you open these coordinates in Google Earth and activate the layer "Google Earth Community" you can inform yourself about the names and strengths of the various test explosions.
In the so-called "Operation Plowshare" the US gouvernment wanted to explore possible applications of nuclear explosive devices for mining and large excavations. The until then not so well-known "side effects" of nuclear explosions doomed those plans and finally led to the Partial Test Ban Treaty.
