A 43-year-old man collapsed Monday afternoon on a trail in Grand Teton National Park and died despite rangers’ efforts to resuscitate him.
The emergency call came in around 4 p.m. for a man who was on his way back down to the Lupine Meadow trailhead after hiking to Surprise and Amphitheater lakes, park spokesperson Denise Germann said.
“There was a witness who saw the man go down,” she said.
The man, who was visiting from out of state, was hiking with three teenage boys. They were two miles up from the trailhead when the man collapsed.
“We responded to the scene with two rangers that began hiking to the scene with medical gear and an AED,” Germann said. “We had two other rangers on the Teton Interagency helicopter and sent two more in the helicopter after that.”
Bystanders were performing CPR when rangers arrived, and park employees were helping coach them by phone.
“Rangers continued CPR and resuscitation efforts,” Germann said. “Efforts were terminated at 5:17 p.m.”
The man’s cause of death is not yet determined pending an autopsy, Teton County Coroner Dr. Brent Blue said.
