FALLING ROCK—British Columbia, Bugaboo Range, West Buttress of South Howser Tower. Thom Nephew (26) was prospecting the ridge approach to the West buttress of South Howser Tower at about 1330 hours on August 16, 1975, for an intended climb. He touched a large and apparently solid boulder, which then fell against his chest and legs, pinning him to the ground and causing a punctured lung, four broken ribs, and severely bruised flesh. The boulder was described as 4' × 3' × 1 1/2'-2', and weighed about 3000 pounds. Slippery rocks caused by recent rain could have contributed to its movement. He called for help, and his two companions, who were some way behind, found him after 8-10 minutes. One companion went for help, and Nephew was evacuated by helicopter at about 1640 hours.
