Overview
- Grand Canyon rangers say two separate heat‑related incidents on June 12 and June 16 led to three deaths despite rapid and aerial emergency response.
- The victims were found on inner‑canyon routes: a 72‑year‑old man on the South Kaibab Trail and a 67‑year‑old man and 68‑year‑old woman on the North Kaibab Trail.
- The National Weather Service issued an Extreme Heat Watch for Monday and Tuesday, warning that parts of the inner canyon could reach or exceed 110°F.
- Park officials are urging visitors to stay off inner‑canyon trails from 10 a.m. to 4 p.m., carry ample water, hike in cooler hours, and know personal limits because rescues can be slow and terrain is harsh.
- Temperatures on inner trails can be tens of degrees hotter than the rim, a difference that can mislead visitors, and the three bodies have been sent to the Coconino County Medical Examiner as investigations continue.
