And in this country, a mountain climber has been rescued after being trapped on a ledge 13,000 feet high in the Colorado rockies. Clayton Sandell has his story. Reporter: This is the moment that Samuel Frappier made it to safety. He spent a frigid night alone and stranded, up long's peak in rocky mountain national park. How was it? Frappier, and a friend set out Tuesday, on an eight-hour hike. But on the way down from the peak, he decided to take a short cut. Soon Frappier found himself stuck, unable to move up or down. He had a new granola bars but ran out of water, forced to spend the night on a rocky ledge in freezing temperatures, wearing only a t-shirt. How cold was it? Extremely cold. It was awful. Reporter: Remarkably, his cell phone worked. He called park rangers for help. It can be very dicey on long's peak. You're dealing with winds. Sometimes almost different weather patterns up there. Reporter: The incredibly steep mountainside at first made a helicopter rescue impossible. Finally, Frappier made it off the ledge. It was a stupid idea to go there. Reporter: A stupid idea? Yeah. Reporter: For "Good morning America," Clayton Sandell, ABC news, Estes park, Colorado.
