The underlying rescue is real and well documented. North Shore Rescue received a call just before 3:30 p.m. on Saturday Oct 3, 2026 about a 16-year-old stuck on a cliff on Crown Mountain, roughly a 40-minute drive north of Vancouver, and search manager Paul Markey told North Shore News the teen had apparently used AI to plan his route up the mountain.

NSR's own Facebook post said: "It turns out that this hiker had somehow got far off the Crown hiking route (we are unclear exactly how/where) and became stranded on a climbing route known as the 'Widowmaker', at the base of its final headwall."

By coincidence, NSR volunteers had been conducting a helicopter training exercise on Crown Mountain earlier that morning.

The specific attribution to Claude came from the rescue team. Markey told CTV News that the teenager rode the gondola up to Grouse Mountain at around 8 a.m. and asked Claude AI to plan a trip to Crown Mountain, and said "Claude has never been in that specific area, has never been on that route, and has never been in the outdoors."

Markey also told CTV News that "A fall would have resulted in significant injury or potentially death."

The affected party disputes the causal part of the story. Gowryluk, 16, is frustrated by news stories claiming he used Claude to plan the alpine scramble, and told CBC News: "People are really taking it out of context, because people think that I planned … or was coerced by the AI to go on the Widowmaker, which is not true."

He says he spent three days planning what was meant to be an eight-hour hike, consulted AllTrails and Google Maps, and admits he cross-referenced some information about the terrain using Claude, but says he mostly used the AI agent to help him with his packing list.

His route was meant to eventually take him through a rugged scramble, but instead he mistakenly turned onto an unmarked route called the "Widowmaker Arete."

The rescuer's own more detailed account also places the wrong turn beyond the suggested route. Markey told Straight Arrow News that Claude had suggested Crown Couloir, a scramble over loose rock, and that Gowryluk, who climbs at a high level in indoor gyms but was on his first outdoor climb, went farther around the mountain and ended up on Widowmaker Arête, a multi-pitch rock climb that requires gear and partners.

Gowryluk told the New York Times, as reported by the Washington Times, that he thought he was going into the Crown Couloir but instead ended up on the steep climbing route , and said the error was with him and not with Claude, since he confused the route that led him towards the Widowmaker for his intended route.
