RENO, Nev. — Authorities said Monday that they are investigating the death of a woman at the counterculture festival known as Burning Man, which is held annually in the northern Nevada desert.
The Pershing County Sheriff's Office said emergency personnel responded to a call about a woman found unresponsive around noon Sunday in Black Rock City — a temporary city erected for the festival, about 100 miles (160 kilometers) north of Reno.
The Burning Man Project's emergency services personnel were unsuccessful in attempted life-saving measures on the woman.
''Our thoughts and condolences go out to the family and friends affected by this loss,'' festival organizers said in a statement. ''We are cooperating fully with local authorities as they investigate this incident."
About a half-dozen other deaths have been reported at the festival since it moved from Baker Beach in San Francisco to the Black Rock desert in 1990. Last year, a 32-year-old California man died from suspected drug intoxication after being found unresponsive on the festival grounds.
Pershing County Sheriff Jerry Allen said in a statement that Sunday's death will remain under investigation until a cause and manner can be determined, which will be updated at the conclusion of an autopsy.
A call to the Washoe County Regional Medical Examiner's Office wasn't immediately returned Monday.
Allen said the woman's name and age won't be released until her relatives can be notified.
