Body: Hello, I’m with the USDA Forest Service’s Innovation and Organizational Learning. We just released a 9 min. video about a fire behavior phenomenon called the Counter Rotating Vortex Pair. Investigators determined this occurred on the El Dorado Fire in 2020, killing Charlie Morton of the Big Bear Hotshots.
Here is the link to the video:
This QCODE will get you more info plus the video.
Editor’s note: The El Dorado Fire burned 22,744 acres in San Bernardino and Riverside counties of California in September to November 2020. It was ignited on September 5 by a pyrotechnic device at a gender reveal party in El Dorado Ranch Park, and quickly spread to the San Gorgonio Wilderness Area of the San Bernardino National Forest.
Burning over a 71-day period, the fire destroyed 20 structures and resulted in one firefighter fatality, for which the couple hosting the party were charged with involuntary manslaughter. Charlie Morton, an experienced squad boss from the Big Bear Hotshots, was killed by the Vortex Pair detailed in the excellent video linked above.
In a report by the Victorville Daily Press, Martin Estacio explained, “When asked by reporters in July how prosecutors will argue the couple’s actions were responsible for Morton’s death, San Bernardino County District Attorney Jason Anderson said the firefighter was “fighting a fire that was started because of a smoke bomb.”
“That’s the only reason he was there,” he said.
A Superior Court judge in San Bernardino on Monday, Jan. 23, dismissed one felony count against the couple accused of setting the El Dorado Fire in 2020 but let stand 29 other charges, including the most serious, according to a January 23, 2023 report by the Mercury-News.
