An experienced climber in California plunged to his death during a rockslide while descending a canyon, authorities said.

Justin Ibershoff, 38, of Los Angeles, was pronounced dead at the scene Saturday in Death Valley, according to Inyo County Sheriff’s Office.

Ibershoff and six pals — who were all “very experienced” canyoneers — were descending Deimos Canyon when he stepped on a rock that moved,  prompting a rockslide, authorities said.

He was swept past two pals and over a 95-foot-tall dry fall, officials said.

Rescuers managed to reach Ibershoff a few hours later via hospital, but he was dead, authorities said.

His body was pulled from the canyon the next day by an Inyo County search-and-rescue team and a California Highway Patrol helicopter, officials said.

“Conditions in that area of the canyon remain unstable and canyoneers are advised to avoid the upper section of Deimos Canyon,” officials said.
