LAS VEGAS (KLAS) -- A third hiker in less than a month has died at the Grand Canyon.

A 50-year-old man from San Angelo, Texas, was found Sunday unresponsive about 100 feet below the Bright Angel Trailhead, according to a National Park Service (NPS) news release. The man's name was not released.

Bystanders and medical personnel responded to Sunday's incident but they were unable to resuscitate the hiker.

NPS said the man was trying to reach the rim after an overnight stay at Havasupai Gardens.

An investigation into the incident is being conducted by the NPS in coordination with the Coconino County Medical Examiner.

On June 16, a 41-year-old man died at the bottom of the canyon after he started the hike out on the same trail. And on June 29, a 69-year-old Texas man died after he was found semi-conscious on the River Trail at the bottom of the canyon. Efforts to resuscitate him were not successful.

The Grand Canyon's website states that an excessive heat warning is in place until July 12 at 8 p.m. (Mountain Standard Time). Hikers are warned of dangerously hot conditions below 4,000 feet elevation, with daytime temperatures reaching 109 degrees at Havasupai Gardens to 115 degrees at Phantom Ranch.

"Day hikers on Bright Angel Trail should descend no farther than 1½ miles from the upper trailhead. Between the hours of 10 a.m. and 4 p.m., hikers should be out of the canyon or at Havasupai Gardens or Bright Angel campgrounds, physical activity is discouraged. All hikers should have adequate gear, including a wide-brimmed hat, sunscreen, salty snacks, sufficient water, and electrolyte mix. Doubling your calorie intake helps maintain your energy," the website advises.
