A skier suffered a fatal fall Sunday in Grand Teton National Park's Death Canyon, the National Park Service said.
A climber in the park in Wyoming called authorities to report having seen someone fall in the Apocalypse Couloir, the park service said in a statement. The climber reported that the skier appeared to be unresponsive.
Teton County Search and Rescue found that Radcliff Spencer, 27, of Wyoming, had fallen while trying to ski the narrow path.
"Resuscitation efforts were attempted but proved unsuccessful due to the nature of injuries sustained," the park service statement said.
Spencer's body was airlifted from the mountain. Four other people in his party were transported out of the canyon by helicopter.
"While the snowpack remains generally stable, hazards still exist and may carry high consequence in technical terrain," the National Park Service statement said.
