The most destructive wildfire in Colorado history started in two places — on the grounds of an international religious cult and from a broken power line about 2,000 feet away, Boulder County Sheriff Curtis Johnson said Thursday, announcing the results of a 17-month investigation into the origin of the Marshall fire. Embers from a fire that was thought to have been extinguished on the Twelve Tribes‘ property at 5325 Eldorado Springs Drive a week before the Marshall fire reignited under high winds and began the Marshall fire, Johnson said.
