A string of heat-related rescues unfolded across the Phoenix area as an extreme heat warning persisted, with hikers suffering heat exhaustion on several trails. In Waterton Canyon, a solo hiker was rescued after experiencing heat exhaustion and returned to their vehicle, with authorities urging planning, hydration, and recognizing fatigue as signals to turn back. On South Mountain’s Bursera Trailhead, rescuers provided hydration and cooling before transporting the adult male to a hospital in stable condition after he could walk down with assistance. Near Scottsdale’s Gateway Loop Trail, two hikers in their 60s were being rescued with extensive manpower, including e-bikes and potential big-wheel or UTV operations, as crews considered multiple tactics amid the high temperatures. A parallel rescue in Phoenix also reported a hiker overheating, receiving hydration and medical evaluation before hospital transfer, all while the region prepared for possibly record heat conditions.
