Climber Deaths in Yosemite, Tahquitz
5/20/13 - A climber died Sunday after he fell climbing the Muir Wall (5.10 A2) on El Capitan in Yosemite Valley, California. The Muir Wall is a 33-pitch line just left of the famed Nose.
The man has been identified as Mason Robison, 38, from Montana. It's believed that Robison pulled a loose block off the wall on pitch 27, which triggered rockfall and severed his dynamic lead rope. His haul line eventually caught him, after he had fallen about 230 feet. He died from the injuries sustained in the fall and the impact of the rope.
Climbers at the base of El Cap notified Yosemite Search and Rescue at 9:15 a.m. They rappelled from the summit to retrieve Robison and his climbing partner, who was physically unhurt. The men were airlifted off the summit.
Two days earlier, 21-year-old Lucas Dunn was killed climbing in Tahquitz Rock, also in California. Greg Davis, Dunn's partner, wrote a detailed report on supertopo.com of the accident. Dunn got caught in rockfall while rappelling after climbing The Vampire (5.11a); he fell more than 300 feet. He did not die on impact; two climbers standing nearby called the sheriff's office, and after lowering to Dunn, began administering CPR alongside Davis. Rescuers arrived via helicopter some time later.
