A 32-year-old hiker died of a suspected heat stroke in Utah’s Zion National Park Monday.
John Henry Wolfe, of Milwaukee, was complaining of heat exhaustion at the end of a strenuous nine mile canyon trail, parks officials said in a statement.
When park medics and EMTs arrived at Wolfe’s location, they found him unresponsive and administered CPR to no avail for about an hour, officials said. His body was airlifted out of the park and the National Park Service and local authorities are investigating.
Heat stroke is caused when body temperature reaches 103 degrees, and can lead to dizziness, confusion and the loss of consciousness, according to the CDC.
The temperature in the park was 95 degrees when Wolfe complained of heat exhaustion, according to KUTV in Salt Lake City
