SEQUOIA NATIONAL PARK, Calif. — Two people are dead after a small plane crashed in a remote area of the Sequoia National Park, the National Park Service said.

Authorities said the identity of those on board is still being determined.

"(The plane) was said to depart from Visalia Airport in California on Friday, September 4 at 11 a.m. and due at Needles Airport in San Bernardino County at 1 p.m. Radar tapes showed last location to be near the Upper Horse Creek drainage in Mineral King wilderness," the National Park Service said in a news release.

Officials said a small fire approximately one-half acre in size associated with the crash is being contained by park personnel.

The National Transportation Safety Board said in a tweet that they are investigating the crash. They identified the plane as a Beech BE-35 airplane. The NTSB said they are not traveling to the scene of the crash at this time.

There is no information about what may have caused the plane to go down.
