CBS News reported on August 31 that a tourist was injured in California after following AI recommendations while climbing Mount Shasta. [^1]

Three novice hikers from Roseville, California, were rescued from Mount Shasta after an attempted summit climb planned with Google's Gemini AI turned into a dangerous overnight ordeal. [^2]

The climbers reached the summit at 7:00 PM local time, which was after the recommended time to begin descent of noon. [^3]

The hikers got lost in Mad Creek canyon, and one participant fell and injured his knee. [^4]

The Siskiyou County Sheriff's Office stated that three amateur climbers from Roseville, California, camped at an altitude of 2,500 meters on August 29 and attempted to summit Mount Shasta on August 30. [^5]

One hiker injured his knee after a fall, and the group spent the night without adequate food, water, warm clothing, or emergency shelter before Forest Service climbing rangers reached them the next morning. [^6]

The hikers reached the 14,179-foot summit at about 7 p.m. on Sunday, August 30, well beyond the recommended noon turnaround time, and began their descent in darkness. [^7]

The hikers used Google's Gemini for information about the route and decisions about what food and how much water to carry, but authorities later said Gemini had advised them to take considerably less food and water than they ultimately needed. [^8]
