VIDEO: Rescuers describe challenges in saving California hikers

FROM CNN WIRES:

(CNN) - On Sunday night, two teenagers called authorities pleading for help after their hike through the Santa Ana Mountains of southern California went awry.

Then their cell phones went dead - meaning that not only were they lost, but so, too, was their link to potential saviors.

Their story took a positive turn Wednesday night, when rescuers came across 19-year-old Nicholas Cendoya. But there was no sign of his hiking mate, 18-year-old Kyndall Jack. Until now.

The Los Angeles County Sheriff's Department rescue team who saved two hikers in California talk about the challenges of locating and saving the teens.
