A 54-year-old French national died in Death Valley National Park this weekend after he spent about an hour exposed to 115-degree temperatures, although the exact cause of his death has not been identified.

According to the Inyo County Sheriff's Department, Guy Brossart was found dead on June 6 at about 3:30 p.m. after failing to return to a tour bus, following a brief stop at the Mesquite Dunes. 

The bus stopped around 2:30 p.m. at the Mesquite Dunes in the Stove Pipe Wells area of Death Valley for the patrons to take pictures," according to a news release from the sheriff's department.

The ambient air temperature was estimated to be 115 degrees at that time. The bus driver instructed the passengers to return to the bus in 10 minutes.

When Brossart failed to return an hour later, the bus driver contacted Death Valley Park rangers who initiated a search. Air support was requested from California Highway Patrol (CHP).

Brossart was found dead in the dunes approximately 400 yards from the parking lot. No foul play is suspected at this time.

The cause of death is under investigation by the Inyo County Coroner’s Office.
