On September 6, 2010 the Boulder County Communications Center in Boulder, Colorado received a radio call at about 10:00 a.m. of a fire in Fourmile Canyon. High winds helped spread the blaze, and within a week, 6,181 acres had been consumed along with 169 homes in what was the most expensive wildfire in Colorado's history. This image, photographed nearly a year later, shows a charred tree trunk left in the wake of the fire.
