A 60-year-old Boulder, Colorado, man was rescued on Sunday morning after he slipped and fell while climbing in a drainage off the South Rim's popular Bright Angel Trail approximately two miles below the rim. A member of his hiking party called 911 and reported the incident to dispatchers. The caller said that the man had fallen only a short distance, but that he had landed on his head and appeared to be disoriented. Park rangers responded and immediately began treating the man for his injuries. Because of the location and the type of injuries, rangers called for the park helicopter and short-hauled the man to a nearby helispot. They then loaded him into the helicopter, flew him to the South Rim helibase, and transferred him to a Guardian air ambulance for the flight to Flagstaff Medical Center. He is being treated there for his injuries. About 18 park staff were involved in the operation.
