Grand Canyon National Park officials stressed the dangers of extreme heat Monday after a man collapsed and died on a hiking trail in Texas over the weekend.
The hiker, Scott Sims, 69, of Austin, was trying to reach Phantom Ranch to spend the night when he was found semi-conscious around 7 p.m. Saturday, the National Park Service said.
He then lost consciousness and a bystander began CPR, the park service said. Paramedics also arrived on the scene but were unable to revive him.
Sims was found on the River Trail, trying to reach Phantom Ranch via the South Kaibab Trail, the park service said. That trail can reach 120 degrees in the shade in the summer, the service said.
“Park rangers strongly advise against hiking in the inner canyon during the day between 10 a.m. and 4 p.m.,” the park said.
Sims’ death is being investigated by park staff and the Coconino County coroner, the park service said. A cause of death was not given in a statement.
A Park Service study of deaths in national parks between 2014 and 2019 found that hiking was the second-deadliest recreational activity, after driving.
