Three hikers have died in heat-related incidents at Grand Canyon National Park in recent days, and officials are warning that extreme temperatures are expected again this week. The deaths occurred on the Kaibab Trail and other areas of the park, where temperatures have exceeded 100 degrees Fahrenheit (38 degrees Celsius).
Details of the Incidents
The first victim, a 65-year-old man from California, collapsed on the Bright Angel Trail on Saturday. Park rangers attempted CPR but he was pronounced dead at the scene. The second victim, a 57-year-old woman from Arizona, was found unresponsive on the South Kaibab Trail on Sunday. The third victim, a 42-year-old man from Nevada, died on Monday after becoming disoriented on the North Kaibab Trail.
All three deaths are believed to be heat-related, according to park officials. The National Park Service advises hikers to avoid strenuous activity during the hottest part of the day and to carry plenty of water.
Heat Warning Issued
The National Weather Service has issued an excessive heat warning for the Grand Canyon area, with temperatures forecast to reach 110 degrees Fahrenheit (43 degrees Celsius) at the bottom of the canyon. Park officials are urging visitors to hike only during early morning or late evening hours and to stay on designated trails.
“Heat-related illnesses can be deadly,” said Grand Canyon National Park Superintendent Ed Keable. “We urge all visitors to take precautions, including drinking plenty of water, wearing light clothing, and avoiding overexertion.”
Safety Recommendations
Park officials recommend that hikers carry at least one gallon of water per person per day, eat salty snacks to replace electrolytes, and avoid hiking between 10 a.m. and 4 p.m. They also advise that hikers turn back if they feel dizzy, nauseous, or have a headache—all signs of heat exhaustion.
The Grand Canyon is one of the most popular national parks in the United States, attracting millions of visitors each year. Heat-related deaths are not uncommon, with an average of two to three fatalities annually, according to park statistics.
