Fresh from a two-day break in his first season as a wildland firefighter, Trenton Johnson was about to begin his first initial attack on a fire when disaster struck. The 19-year-old Missoula man had just finished a two-week deployment mopping up a fire in Utah for Grayback Forestry Inc., an Oregon-based business with a firefighting contract to the U.S. Forest Service. His 20-person ground crew had been split in half to help with a rash of small forest fires around Missoula following last weekend’s lightning storm. Ten went to the Bitterroot National Forest. Johnson headed north to Seeley Lake, assigned to a lightning strike on Rice Ridge near Florence Lake. The half-acre fire didn’t even have a name when he arrived Wednesday afternoon.
