A 75-year-old man died during a trip to Big Bend National Park on Thursday, the National Parks Service said in a news release.
The unidentified man from Houston was found just before 8 p.m. on the Chimneys Trail, about a half-mile from the trail head.
Officials said there was no obvious cause of death, but emphasized that visitors should take precautions with the extreme summer temperatures Texas is experiencing. On Thursday afternoon, the temperatures on Chimneys Trail were over 104.

Officials said hikers should be prepared to carry and drink 1 gallon of water per day and plan on being off of the desert trails by at least noon to avoid the day’s peak heat.
The Chimneys Trail is a moderately-difficult, 5-mile round trip hike to a series of prominent volcanic formations in the western part of the park, the release said.
Officials did not say whether the man was hiking alone or how long he was in the park.
