A hiker died on Sunday while attempting to reach the south rim of the Grand Canyon in Arizona, using a popular trail.

Grand Canyon National Park’s office of communications said in a press release that a 50-year-old man from San Angelo, Texas, died after hiking back to the rim after an overnight stay at Havasupai Gardens.

At about 2 p.m. on Sunday, the Grand Canyon Regional Communications Center received a report of an unresponsive hiker on the Bright Angel Trail, nearly 100 feet below the trailhead.

Bystanders performed CPR on the man as Xanterra Fire and Security and National Park Service (NPS) medical personnel responded from the top of the rim.

This is the second time in the last two weeks that a hiker from Texas has died in the national park.

On June 29, 69-year-old Scott Simms of Austin, Texas, was trying to reach Phantom Ranch via the South Kaibab Trail for an overnight stay when he was found semiconscious around 7 p.m.

Sims collapsed on the River Trail, about halfway between the Silver Bridge and Black Bridge near Phantom Ranch, according to the NPS. Temperatures on exposed parts of the trail can reach 120 degrees in the shade, the agency said.
