Teen hiker rescued from North Shore cliff after AI-planned route went wrong

A 16-year-old hiking solo on the North Shore got stranded on a cliff after an AI-generated route sent him up terrain beyond his ability. North Shore Rescue plucked him from the base of a rock-climbing section on Crown Mountain by helicopter on Saturday afternoon.

The boy started at Grouse Mountain around 8 a.m. Saturday and had plugged his planned route into an AI system. The bot told him to ascend Crown Mountain by gully — a straightforward description that didn't match the actual terrain. When he got there, he found himself at the base of a steep rock-climbing route with no way forward or back. He called for help just before 3:30 p.m., and rescue wrapped up around 6:30 p.m.

Paul Markey, search manager for North Shore Rescue, said the hiker was well-equipped — backpack with headlamp, hiking boots, cell phone battery pack, windproof jacket — and made the right call by staying put. "The boy was very scared. He definitely feared for his life," Markey said. Two rescue techs were hoisted down to him and lifted him to the helicopter.

Markey said this was the first time he'd encountered someone following an AI-planned hiking route. "It put him into a situation which was beyond his abilities, so things could have gone sideways pretty quickly," he said. He's urging hikers to use established mapping tools like Gaia GPS, CalTopo, or AllTrails instead. "Be cautious when getting routes and information suggested through AI. You can't just blindly follow what AI is proposing to you. You need to question the information and just see whether it makes sense or not."

Saturday was busy for North Shore rescuers: they also responded to an overdue group of hikers (who were eventually located), a hiker with an ankle injury near Cypress Mountain, a group of lost hikers on Goat Mountain, and a mutual aid call to Lions Bay SAR for an ankle injury on Brunswick Mountain. As fall approaches, Markey is urging people to bring headlamps, micro spikes for boots, and warm clothes for colder temperatures.
