ZION NATIONAL PARK — A hiker from Wisconsin died of heat exhaustion at Zion National Park on Monday.
First responders were called after John Henry Wolfe, 32, of Milwaukee, complained of heat exhaustion at the exit route of the Left Fork of North Creek, National Park officials said in a statement.
Park medics and EMTs arrived and found Wolfe unresponsive. They administered CPR for one hour before stopping based on guidance by St. George Hospital medial control. Wolfe's body was extracted from the area with a long line from a helicopter.
The National Park Service and Washington County Sheriff's Office are investigating the death.
Zion National Park this summer has dealt with a spike in heat illness-related calls due to larger crowds and hotter weather.
Park officials urge visitors to stay hydrated, have essential sun protection and to pace themselves. The park has water filling stations at its visitor center, as well as the Zion Lodge, the Grotto and the Temple of Sinawava.
Officials also recommend that visitors wear hats, sunglasses and lightweight clothing, as well as apply sunscreen often. In addition, they advise that people take frequent breaks in shade, minimize sun exposure, and avoid being active during the hottest parts of the day.
