California, Yosemite National Park, Indian Caves Area. On 25 March Jon Martin Spangler (18) and five companions were bouldering at Indian Caves. Spangler lost his grip and traction, slid 6 to 8 feet down an angle of rock, bounced and Hipped around, then fell free for 20 to 25 feet and landed on a smaller boulder feet first. He suffered a broken right foot, broken pelvis, and broken back. He was transferred to a stretcher and then to the hospital.
