A helicopter carrying six people crashed on Friday night near the California-Nevada border, and no survivors have been located as of Saturday morning, the authorities said.
The Federal Aviation Administration said that the Eurocopter EC130 helicopter crashed at around 10 p.m. local time near Nipton, Calif., an unincorporated community about 60 miles south of Las Vegas in eastern San Bernardino County.
It was unclear on Saturday morning where the helicopter departed from and where it was headed.
Officials at the San Bernardino County Sheriff’s Department were made aware of the downed aircraft at 10:12 p.m. local time, Mara Rodriguez, a public information officer with the department, said in a statement, adding that the scene of the crash was determined to be east of Interstate 15, near Halloran Springs Road.
The National Transportation Safety Board and F.A.A. are investigating the crash, officials said. Representatives from the N.T.S.B. are expected to arrive at the site on Saturday.
