Grand Teton National Park rangers yesterday assisted a 57-year-old Jackson man with an injury who had been climbing near the Black Rock Chimney on the Grand Teton. Jim Williams was leading a client on a guided trip of the Grand Teton for a park concessionaire when the snow that he was standing on collapsed, causing him to take a short fall. In the process, park officials say Williams caught a crampon on the ice and was injured. Rangers say Williams was able to get himself and his client through technical terrain from the Black Rock Chimney to just above the Lower Saddle of the Grand, descending across rock, ice and snow and making multiple rappels. Park rangers met Williams and his client at 3:15 pm just above the Lower Saddle. After assessing the feasibility of a ground-based evacuation via rescue litter, a decision was made to fly Williams to the valley floor via helicopter. To conduct that aerial evacuation, however, rangers requested a ship from Yellowstone National Park since neither of the two Teton Interagency contract helicopters was available. From Lupine Meadows, Williams was able to transport himself to seek medical care. Rangers are commending Williams for his self-rescue efforts while on the mountain with his client to the extent that he did.
