In RJ Secor's report of a dangerous stream crossing near Tehipite Dome, he wrote:

Here is your report: "Accidents in North American Mountaineering", 1977, p.19-20, and also "Off Belay", December 1976.

Mitchell R. Haydon died while rappelling at Pinnacles National Monument. He was using a prusik backup to the rappel. The prusik caught, and he could not release it. The prusik was connected to a "waist tie of 6 loops of 1 inch tubular nylon webbing", and he was unable to release it. His breathing was constricted, and after about 25 minutes, he lapsed into unconsciousness, and started convulsive vomiting. 10 minutes later, he was lowered to the ground, but his airway was blocked and CPR efforts failed.
