Time-lapse movie of the Las Conchas Fire, Los Alamos County, June 26 2011. Time-lapse exposures are from a vantage point just north of Santa Fe, home of Polly White & Michael Zeiler. Los Alamos city and labs can be seen to the right of the fire.
Witness: I’ve been contacted by a fire scientist and learned that this video is a rare photographic record of a phenomena called “horizontal roll vortex” fire. This type of fire was first identified in 1956 and is not well understood.
A “horizontal roll vertex” fire as seen in this video has a clear rotation of the fire column and is associated with extreme crown fires. This fire is certainly extreme, having grown to 43,000 acres on its first day.
