**EMBARGO: SEATTLE/TACOMA** The Cle Elum wildfire in central Washington began Monday, Aug. 13, 2012. Fueled by high winds it burned 24 structures and forced evacuations of residents nearby.
BOISE, Idaho (AP) - For wildland firefighter Anne Veseth, the danger came not from out-of-control flames, but from a falling tree on Sunday, ending her life at just 20 years.
Exactly what happened is now the subject of a federal investigation. Veseth and her crew were trying to extinguish the 43-acre Steep Corner fire near Orofino.
U.S. Forest Service spokesman Phil Sammon says they were establishing and reinforcing a fire line on one perimeter of the blaze.
At least two federal investigators from the U.S. Department of Labor's Occupational Safety and Health Administration were on the scene in Orofino, looking into Sunday's accident.
An investigation could take up to six months, says Labor Department spokeswoman Deanne Amaden in San Francisco.
