Brad Gobright , an acclaimed American free solo climber, has died after falling nearly 1,000 feet while rappelling a well-known route in Mexico with a rope, the authorities said.

Mr. Gobright, 31, fell to his death on Wednesday from a rock known as El Sendero Luminoso, or the Shining Path, in the Potrero Chico national park in northern Mexico, the Mexican civil defense authorities said in a statement on Thursday.

Mr. Gobright, a native of California, was hailed as one of the world’s best free solo climbers, a technique that uses no ropes. He set a speed record in 2017 — 2 hours 19 minutes 44 seconds — at the popular climbing route called the Nose on El Capitan in Yosemite National Park. It has since been surpassed.
