A Texas hiker died on Sunday while attempting to climb the Bright Angel Trail in Grand Canyon National Park.
The National Park Service said its communications center got a report of an unresponsive male at 2 p.m., but bystanders and first responders were unable to revive him.
The National Park Service and Arizona’s Coconino County Medical Examiner are investigating the 50-year-old’s death to identify the reason.
This is at least the fourth death this year at the park, which is considered America’s worst.
In May, a 58-year-old was recovered in the Colorado River, and in June, the bodies of a 41-year-old and a 69-year-old were located during separate searches.
So far, the NPS has not directly linked any of the recent deaths to severe heat, but it will likely be a component in the investigation.
Rangers warn that temperatures often approach the century mark, particularly below 4,000 feet, where recent daytime highs were from 115 to 120 degrees.
The Grand Canyon National Park is considered dangerous due to its rocky topography and unpredictable weather conditions, which include scorching heat and abrupt monsoon flooding.
According to NPS data, approximately 17 individuals die each year at the park, with falls and medical difficulties being the leading reasons for death.
Every year, more than 4 million people visit the 1,904-square-mile park, making it one of the most popular attractions in the country.
Many visitors come to observe the Grand Canyon’s formation, which is believed to be billions of years old.
Park authorities advise hikers to stay no more than a mile and a half from the trail during heat alerts.
Hikers are also strongly recommended to bring enough equipment, drinks, and food to meet their energy requirements and double their calorie intake.
According to the park service, all paths on what is known as the canyon’s South Rim are available all year.
