The Cannikin Nuclear Bomb being lowered into the shaft at ground zero. Water became such a problem in the shaft that pumps were run constantly to remove it.

 

Ground Zero Today. Notice Cannikin Lake in the background. This is the subsidence crater that formed from the collapse of the chimney into the void. White Alice creek flowed into this crater for 10 months until it filled up and emptied into the Bering Sea. Some measurements indicate that Radioactive nucleotides are flowing into the Bering Sea. The area beneath the surface is completely contaminated with the radioactive materials Tritium, Krypton, and strontium-90.  No technology exists to remove that contamination.
