3 elderly hikers die on Grand Canyon's inner trails as temperatures spike

Three elderly hikers have died from apparent heat-related illnesses while traversing the Grand Canyon's inner trails amid a significant temperature spike. The National Park Service confirmed rangers and emergency personnel responded to two separate incidents on June 12 and June 16.

Temperatures in the Inner Canyon can soar above 109 degrees Fahrenheit during midday hours, posing extreme risks. In the first incident on June 12, a 72-year-old man was found deceased on the South Kaibab Trail. Just four days later, on June 16, a 67-year-old man and a 68-year-old woman were discovered dead on the North Kaibab Trail.

Emergency responders arrived at the scenes to find the hikers already deceased. Investigations into the exact causes of death are ongoing, though heat-related symptoms are the primary suspected cause for all three fatalities. The hikers' bodies were transported to the Coconino County Medical Examiner's office for further examination.

These tragic deaths follow another recent fatality in the park, where a teenager died from apparent heat-related causes after attempting a strenuous round-trip hike from the South Rim to the Colorado River earlier in June. Last year, an elderly man also died while attempting to reach the Colorado River for an overnight stay at Phantom Ranch.

In both cases, the deceased hikers were hiking trails in the Inner Canyon, where temperatures can exceed 109 F in the shade during midday hours.
