British Columbia, Purcell Range, Commander Mountain. On 27 July David Jones, John Christian, Murray Foubister, and Jan Atlung (26) were attempting a new route on a rib of the NE face of Commander Mountain. David Jones led a rope pitch, anchored and belayed his second, then continued up another pitch. Meanwhile Jan Atlung climbed the first pitch and had just clipped into the belay anchor when the last man looked up to see a falling rock outlined against the sky some 500 feet above the leader. Jan was sitting with his back to a 20-foot wall when struck by direct impact by the falling rock. The second called for Jones to come down while the last man came up. There was adequate room at the belay site on a large ledge. Jones drove several more pitons while the other two rigged up prussiks and carabiner brakes, examined Atlung to find the extent of the injuries, and he put him on his back, then the two others lowered them 200 feet down the face as Jones walked down backwards. They then used a leap-frog method to lower Atlung a further 400 feet down a snow and ice slope to safety. Jones then went for help returning in three hours with 20 people, doctors, a stretcher etc. They proceeded to move the victim (whose condition had deteriorated considerably) but after an hour the doctor called for a complete stop and ordered a helicopter.
