PROVO — A hiker who fell 10 feet down a mountain then spent nearly two hours in a mountain pool should have no lasting injuries, Utah County officers said.

The 21-year-old woman was hiking Tuesday afternoon around 12:30 p.m. in the area of First Falls above Sundance up Provo Canyon when she came to a steep area and slipped down, said Utah County Sheriff's Deputy Collin Gordon.

She fell from 10 to 12 feet into a waist-deep pool of water and was stranded with no way to get out or hike down, as it was 30 feet down. Gordon said she was not injured from the fall but began showing severe signs of hypothermia.

The friends she was hiking with were able to get a cell phone from other hikers and call for help.

Utah County Search and Rescue Crews and medical personnel were able to hike in to the woman and a medical helicopter was used to get her off the mountain, back down to the parking lot near the Aspen Grove trailhead.

Gordon said she was taken by ambulance to Utah Valley Regional Medical Center, where he expected her to be released by Tuesday night.

"We're just happy with the way it resolved," Gordon said.
