GRAND CANYON, AZ – National Park Service (NPS) officials have confirmed the deaths of three hikers within a four-day span due to suspected heat-related illnesses as temperatures in the canyon soared.
Fatal Incidents on Major Trails
Park rangers and emergency personnel responded to two separate incidents in the Inner Canyon between June 12 and June 16. According to an NPS news release, all three victims were found deceased upon the arrival of rescue crews.
- June 12: A 72-year-old man died while hiking the South Kaibab Trail. Park officials noted that this popular trail offers expansive views but provides almost no shade and has no water sources past the trailhead during summer months.
- June 16: A 67-year-old man and a 68-year-old woman died along the North Kaibab Trail. This route is widely recognized as the least visited and most physically demanding of the Grand Canyon’s major inner canyon trails.
Extreme Inner Canyon Temperatures
The park service warns that daytime temperatures in the shade within the Inner Canyon can easily reach 109 degrees Fahrenheit around midday. Officials strongly advise all visitors to completely avoid hiking in the Inner Canyon during peak daylight hours.
An official investigation into the exact cause of death for all three individuals remains ongoing.
Understanding Heat Risks
According to data from the Centers for Disease Control and Prevention (CDC), heat remains the top weather-related killer in the United States. Heat-related illnesses, such as heat stroke and heat exhaustion, occur when the body loses its ability to cool itself down.
Park officials emphasize that older adults, young children, and individuals with pre-existing medical conditions face the highest risk during extreme summer heatwaves.
