Brad Haugh still remembers the sound of his heartbeat. It thundered in his chest. Two hundred beats a minute. With a fire behind him and a ridge ahead of him, this smoke jumper needed every pulse of power his heart could give in order to escape with his life. He was one of forty-nine firefighters caught in a wildfire on the spine of Storm King Mountain, seven miles west of Glenwood Springs, Colorado. Fourteen of them lost their lives. They were overrun by flames that Haugh estimated to reach a height of three hundred feet. The wall of heat required only two minutes to race a quarter of a mile up the mountain, reaching a speed of eighteen miles per hour. Temperatures reached two thousand degrees, hot enough to incinerate the tools dropped in its path. “People were yelling into their radios, ‘Run! Run! Run!’ I was roughly one hundred and fifty feet from the top of the hill, and the fire got there in ten or twelve seconds. I made it over the top and just tumbled and rolled down the other side, and when I turned around, there was just this incredible wall of flame.”
