A teenager who was stranded 13,000 feet high on the side of Longs Peak for more than a day was flown to safety early Wednesday evening after an all-out rescue effort.

Rescuers reached the 19-year-old Canadian climber just before 6 p.m. and announced at 6:30 p..m. that he had been flown by helicopter to the landing zone at Upper Beaver Meadows in Rocky Mountain National Park.

He was taken by ambulance to Estes Park Medical Center for evaluation. Park officials said he could walk and talk.

Samuel Frappier, of Quebec, used a cellphone to call for help late Tuesday from Broadway Ledge high on the mountainside above Lambs Slide, according to park officials. Rangers also talked to him Wednesday morning.

Park spokeswoman Kyle Patterson said Frappier was stuck in a “extremely precarious” spot.

Frappier had no experience as a mountaineer and no technical climbing equipment. He was wearing only cotton clothes and tennis shoes, Patterson told 7News.

The rescue team faced multiple hazards that hindered its efforts throughout Wednesday including rapid melting conditions, which caused significant snow, ice and rock falls.

As the area became shaded in the afternoon, conditions stabilized somewhat and became more suitable for rescue.

Frappier, whom officials described as “physically fit,” had been hiking and climbing with a friend Tuesday, but the pair became separated while ascending the western side of Chasm Lake via Lambs Slide.

Frappier became stuck while descending the ledge. He did not report any injuries when he called officials Tuesday evening but said that he could not go up or down, according to park officials.

There was no moisture overnight, but temperatures dipped into the 30s and winter conditions exist above 9,000 feet.

The initial rescue team arrived at the Chasm Shelter at the base of the east face of Longs Peak late Tuesday. By the time the rescue effort was finished, 28 team members and several helicopters were involved.

A Teton Interagency helicopter from Grand Teton National Park carrying four rangers was called in from Wyoming to assist in the rescue.

These rangers were experts in short-haul recovery of people from places where it is impossible or too dangerous to land a helicopter.

Short-haul rescues typically involve lowering one ranger by rope to the stranded person and lifting them out. They are also trained to administer emergency medical care. The park service and Bridger-Teton National Forest jointly contract two Bell Jet Ranger helicopters each summer for firefighting and rescue operations.
