A Montana rock climber died Sunday afternoon while attempting to ascend El Capitan in Yosemite National Park, park officials said.
Mason Robison, 38, and his partner were 2,300 feet above the Valley floor on the Muir Wall route when the accident occurred at about 9:15 a.m.
Robison climbed 30 feet above his protection on a loose flake. The flake suddenly pulled out of its block, severing Robison's climbing rope and causing a rockslide. He fell 230 feet and was left dangling by his haul line.
Park rangers and members of Yosemite Search and Rescue rappelled from the top of El Capitan to retrieve Robison's body and his partner. Both were airlifted off the summit by helicopter.
It was the first climbing fatality of the year in Yosemite, park spokesperson Kari Cobb said.
