1953: Las Vegas Mushroom Cloud Chris August 18, 2012 1950-1959, Places 6 CommentsFavourited 872 times Add to favourites 6 Responses Suggymoto August 18, 2012 Anybody think that if this happened nowadays the shit would seriously hit the fan? Terrifying. Reply LREKing August 20, 2012 Funny stuff. In the artist’s renderings, the cloud is in different places. And the one that appears to be an actual doesn’t show the mushroom. Nice try, Las Vegas. Reply RickJ August 22, 2012 The second image above (the photograph) is apparently the real thing. I even found it shown in this video: http://www.lvrj.com/multimedia/First-Atomic-Detonation-at-Nevada-Test-Site-114744359.html I remember the days when we were still testing above ground. But, I lived in Kentucky, never saw the mushroom. Btw, I believe the mushroom shown may have drifted off the column, making it look like a single cloud floating along. Reply Ian August 29, 2012 All I can think of when I see this is Fallout New Vegas, just because, well, ya know… Reply Owen September 14, 2012 Ian, you beat me to it. Reply Steve September 22, 2012 Out of all of those number two is real. If a weapon is detonated at a high enough altitude there is no stem to the “mushroom.” The stem is not from the fireball rising, but from the vacuum created by the blast after the shock wave has passed. The dust meets at the center and rises… when it contacts the the remnants of the fireball it creates the mushroom look. There were plenty of tests at the NTS in the 1950s that were air drops at relatively high altitudes that did not create the stereotypical mushroom cloud that popular thought stows upon nuclear detonations.
