Park rangers said the communications center received a call around 4:20 p.m. Monday asking for emergency assistance on the Hot Springs Canyon Trail.
When rangers arrived, they found a 53-year-old woman in distress. They performed CPR for more than an hour and called for backup, but were unable to revive the walker.
The park says she and her family were visiting the park at the time and warned that temperatures in Big Bend were beginning to surpass 100 degrees.
Park rangers are reminding people to be aware of the dangers of extreme heat and recommend carrying and drinking a gallon of water a day. They plan to be off the desert trails by noon.
