A Teen Trusted Claude's Route Through the Canadian Mountains — Then Rescuers Had to Pull Him Off a Cliff

How a teenager nearly died by trusting AI for mountain navigation

16-year-old Bryce Vincent Hourigan rode the gondola to the summit of Grouse Mountain in British Columbia and made a simple request to Claude: plan a route to nearby Crown Mountain and back. The chatbot agreed to help. Hours later, the teen was rescued by a North Shore Rescue helicopter from the sheer Widowmaker Arete climbing route — one of the most dangerous in the region.

The Widowmaker Arete is a 1,700-foot wall of black rock with jagged outcroppings, requiring ropes, carabiners, a clear ascent plan, and serious experience. The route is officially described as "mostly an easy rock slope with short steep sections involving cracks and irregular rock surface." Crown Mountain normally takes 8 hours — hikers climb more than 2,000 feet and are rewarded with panoramic views of Greater Vancouver, the Fraser Valley, and the Capilano watershed. Trail guides warn that the route isn't for beginners.

Hourigan, an avid climber with indoor rock-climbing experience, was descending from Crown Pass, passed through the Crater Slabs, and entered a valley littered with boulders. This is where Claude's directions began leading him in a completely wrong direction. The teen ended up at the final sheer drop of the Widowmaker Arete — a rock formation you can't get out of without equipment. When Hourigan started climbing, he realized the terrain was too steep, and he got stuck at the base of the cliff. He called his mother, then called for rescue.

Police notified North Shore Rescue, which dispatched a helicopter. However, Hourigan was too close to the rock wall — the rotors couldn't get close enough. Two rescue team members were lowered on a rope to bring the teen up and evacuate him. He was taken to the rescue base near Cleveland Dam.

In its report, the rescue team noted that Hourigan was "far" from the planned route. This is the first case in North Shore Rescue's history of someone needing to be rescued because of incorrect AI directions. However, it's not the first incident in the backcountry of southwestern British Columbia, where travelers increasingly rely on inaccurate digital maps.

A growing trend of dangerous trust in apps

In July 2026, three hikers were rescued after planning a route on the Howe Sound Crest Trail using Google Maps. The app gave wildly incorrect time estimates: it suggested a route that normally takes 14+ hours was doable in 5+ hours.

Search manager Paul Markey warned climbers against blindly trusting AI directions. "In this particular case, the boy was well-equipped for hiking and scrambling — he had a headlamp, good clothing, quality boots, a spare battery, and extra food. But he was completely unprepared and unequipped for rock climbing," Markey said.

"Claude has never been in the area where this 16-year-old boy ended up. AI can only go so far in describing terrain. There's a definite trend toward using electronic apps instead of map-and-compass skills. But that's absolutely no substitute for good navigation training and education."

Markey also noted that some apps provide too much information. "We've found that some apps have identified trails in areas where our preference as a rescue team would be for those routes not to be marked at all," he said, adding that people see routes that look like good trails and end up in trouble.

"The bottom line: don't blindly rely on AI as a route-planning tool. It can never replace good education, good preparation, good experience, and good decision-making in the field."
