PHOENIX -- A woman was rescued from South Mountain on Saturday morning after becoming dehydrated.
Phoenix Fire Capt. Jonathan Jacobs said fire crews were called to the mountain around 9:30 a.m. for a 57-year-old woman who felt fatigued and light-headed while hiking the north side of the mountain.
Fire crews from Phoenix, Tempe and Chandler responded and hiked about 40 minutes to the woman's location.
Jacobs said although the woman was stable, rescue crews decided to airlift her off the mountain because a big-wheel operation would likely have taken more than an hour.
She was flown to the base of the mountain and transported to a hospital by ambulance.
"A lot of really positive things happened," Jacobs said. "The hiker knew exactly where she was, knew where she entered and had water. ... That really helps us a tremendous amount when you know where you're at."
The woman was also hiking with a companion.
Jacobs is reminding people to be careful when hiking in the triple-digit heat. He said hikers should hydrate before, during and after their hike, and rest in a shaded area if they feel fatigued.
"It catches up with you," he said. "Don't underestimate the mountain, don't underestimate the heat, and then really be realistic about what you're trying to achieve that day."
