Kyndall Jack, 18, of Costa Mesa, was shouting for help as she clung to the side of a steep cliff in Trabuco Canyon in Cleveland National Forest southeast of Los Angeles, ABC News reported. Rescuers rappelled down to her rescue and she was airlifted to University of California, Irvine Medical Center to be treated for severe dehydration.
Her companion, 19-year-old Nicolas Cendoya, was found alive Wednesday night, authorities said.
Lt. Jason Park of the Orange County Sheriff's Department said Cendoya was "dehydrated and very confused" when found and was being taken to a hospital, the Los Angeles Times reported.
Cendoya was found a half mile from the pair's parked vehicle.
The pair had gone out hiking in the rugged hills on Easter Sunday. They used their cellphone to call 911 Sunday evening but the phone went dead before authorities could pinpoint their location.
Rescuers aided by bloodhounds had been searching for the youths ever since.
