The “Baker” explosion, part of Operation Crossroads, a nuclear weapon test by the United States military at Bikini Atoll, Micronesia, on 25 July 1946. The wider, exterior cloud is actually just a condensation cloud caused by the Wilson chamber effect, and was very brief. There was no classic mushroom cloud rising to the stratosphere, but inside the condensation cloud the top of the water geyser formed a mushroom-like head called the cauliflower, which fell back into the lagoon (compare with this image, a photo taken slightly later, after the condensation cloud had cleared). The water released by the explosion was highly radioactive and contaminated many of the ships that were set up near it.  The column of water under the condensation cloud in this picture is 6,000 feet tall, 2,000 feet wide.

I am a Librarian. To be honest, I wouldn't want to do anything else. I have a strong background in architecture, computer technology, English literature, Internet applications, web site design, film studies and modern art. I would like to use this page to express my personal musings and experiences on news, pop culture, nature, art, science, technology and what ever becomes a curiosity.
