A 64-year-old woman died at Big Bend National Park in Texas on Monday after she collapsed on a trail, the National Park Service said Tuesday.
Rangers were called to the Hot Springs Canyon Trail around 2:45 p.m. Officials tried CPR, and a helicopter was called in to transport the hiker, but she died, the park service said.
The incident at Big Bend, in southwestern Texas near the U.S.-Mexico border, occurred the same day a high temperature of 97 degrees was reported in nearby Rio Grande Village, according to the National Weather Service.
Hot Spring Canyon Trail has no shade or water, the park service said.
"While we can’t conclude that weather was a factor in this incident, March reminds us that the beauty of Spring often brings dangerously hot temperatures to Big Bend," the park's acting deputy superintendent, Rick Gupman, said in a statement. "Our entire Big Bend family extends our deep condolences to the hiker’s family and friends.”
The hiker's name was not released. Big Bend National Park encompasses around 800,000 acres.
