On Monday, August 27, 2012, the Yosemite Emergency Communications Center received a 911 call from two climbers (one male and one female) who had had fallen on what they had believed to be the first pitch of Snake Dike, a climbing route on the Southwest Face of Half Dome. In fact, the climbers were approximately one quarter of a mile east of the Snake Dike route.
For reasons unexplained, the climbers did not place any anchor gear for the climber who was belaying. The lead climber started up the route, climbing 40 feet of easy (5.5) slab with no protection up to a shallow roof (small piece of granite jutting out from the face). Under the roof he placed a piece of protective gear (#.3 cam). He then tried to turn (move past) the roof and fell. The piece of protection held. He tried again and fell, and again the piece held. He tried a third time and fell; this time his one piece of protection pulled out. He fell down to the belay ledge, struck the ledge next to his climbing partner, and fell 40 feet farther until the rope became taut, pulling the belayer off her belay ledge. They both came to rest 50 feet below the belay ledge, on the next major ledge.
Although injured, the pair of climbers started hiking down the slabs in an attempt to self-rescue. They encountered another climbing party who had cell phones. Feeling that they were unable to continue their descent, the injured climbers borrowed a cell phone and called 911. The injuries sustained by the belayer sounded significant, so two medics from the Helicopter Rescue Team (HRT) prepared for an immediate rescue. The park helicopter transported the two HRT members by short-haul to the subjects' location. After assessing the injured belayer, the rescuers prepared her for a short-haul in a litter to Ahwahnee Meadow, where she was then transferred to an awaiting medical evacuation helicopter. She was flown to a trauma center in the Central Valley; her injuries included a pneumothorax (punctured lung), a fractured pelvis, and two fractured vertebra. The lead climber was also short-hauled to Ahwahnee Meadow; however, his injuries did not necessitate a litter. He was transported by a park ambulance to the Yosemite Medical Clinic.
In light of this incident, please keep in mind:
