VANCOUVER, Wash. (AP) - Authorities say a 25-year-old California woman was found dead from an apparent drug overdose at the Rainbow Family Gathering in Gifford Pinchot National Forest.
Skamania County officials told The Columbian newspaper an autopsy will be performed on the unidentified woman to determine her official cause of death.
Sheriff Dave Brown says it was unclear on Wednesday what drug or drugs might have triggered the woman's death.
Earlier in the week, an unidentified camper died from what was believed to be natural causes.
Officials estimate around 20,000 outdoors enthusiasts, peace activists and spiritual seekers attended this year's Rainbow Family Gathering in Washington.
The event officially ends Thursday.
