The Hot Springs Trail takes hikers above the Rio Grande for 3 miles of rugged desert and cliffs. Officials say this trail is dangerous to trek in the afternoon heat because there is no shade or water.

On Monday, the Weather Channel reported that the high temperature at the park was 85 degrees.

"Big Bend National Park staff and our partners are saddened by this loss," said Acting Deputy Superintendent Rick Gupman. "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. Our entire Big Bend family extends our deep condolences to the hiker’s family and friends."
