A team of Grand Teton National Park rangers, emergency medical personnel, Teton County Search and Rescue (SAR) team members and a contract helicopter quickly swung into action Sunday morning, May 17, to rescue four backcountry ski mountaineers who were involved in an avalanche on the northeast face of Mount Moran. Luke Lynch, age 38, of Jackson, Wyoming was killed in the avalanche and one of his companions, Stephen P. Adamson, Jr., age 42, sustained life-threatening injuries, prompting evacuation by helicopter. Two other companions, Brook Yeomans, age 37, with minor injuries, and Zahan Billimoria , age 37, who escaped injury, were also evacuated via helicopter as continuing avalanche activity and a steady cycle of snow squalls across the Tetons made the multi-staged rescue operation more challenging. All three survivors were local residents of Jackson, Wyoming.
