Three California hikers relied on AI to plan their climb of Mount Shasta; The 8-hour walk turned into a 16-hour ordeal that left them injured, stranded overnight, and ultimately rescued. World news

Three novice hikers from Roseville, California, were rescued from Mount Shasta after a summit attempt they had planned with substantial help from Google’s Gemini AI turned into a dangerous nighttime experience. The three men expected the climb to take about eight hours and brought food and water based in part on that plan. Instead, they reached the 14,179-foot summit around 7 p.m. on Sunday, August 30, well past the recommended noon time. Their descent was made in the dark and they eventually veered off route into the Mud Creek Canyon drainage. One hiker injured his knee after a fall, his phone used for navigation lost power, and the group spent the night without adequate food, water, warm clothing, or emergency shelter before Forest Service rangers caught up with them the next morning.
California Hikers Started Climbing With AI-Assisted Plan
The three men left the Clear Creek Trailhead on the southeast side of Mount Shasta on Saturday, August 29, and established a base camp at about 8,400 feet. According to accounts from the U.S. Forest Service and the Siskiyou County Sheriff’s Office, the group were novice climbers and had used several digital sources while preparing for the trip, including Google’s Gemini, YouTube and the AllTrails mapping app. Gemini was used to obtain information about the route, as well as to make decisions about what food and how much water to carry. The group planned a roughly eight-hour climb and left their camp around 3 a.m. Sunday with backpacks. Authorities later said that Gemini had advised them to take much less food and water than they ultimately needed.
They reached the summit seven hours after the return time.
The rise lasted considerably longer than expected. The hikers did not reach the summit until approximately 7 p.m., although Mount Shasta climbers are advised to turn around before noon if they have not reached the summit. The rule is designed to allow enough natural light for descent and reduce the risk of people becoming stranded. Arriving at the summit approximately seven hours after the recommended turning point, the group began their return in the dark. The Forest Service said the climbers had been advised to turn around during the climb, but they continued and eventually reached the summit. Their roughly eight-hour plan had effectively turned into a much longer task before they even began the descent.
Darkness, dead batteries and a wrong turn left them stranded
About an hour after leaving the summit, the hikers contacted the Siskiyou County Sheriff’s Office for directions, but ultimately deviated from the established route and entered the Mud Creek Canyon drainage. They had been using AllTrails for navigation, but the phone running the app ran out of battery and the backup charger failed. The Forest Service said one member also had a Garmin watch, although the group relied primarily on visual navigation during the descent. At about 11,500 feet, one of the hikers fell and injured his knee. The group finally stopped around midnight at the steep drainage and spent the night there. They lacked enough food and water to get through an unexpected night and had no adequate warm clothing or emergency shelter.
The rangers found them the next morning.
U.S. Forest Service rangers reached the stranded hikers around 9:30 a.m. on Monday, August 31. The rangers provided first aid to the injured climber, as well as food and water for the group. Siskiyou County Search and Rescue volunteers were deployed to assist with the operation. Helicopter assistance was complicated by conditions at higher elevations, and the Forest Service reported difficulties with attempts to hoist helicopters. Therefore, the hikers continued down the mountain with the climbers. They finally arrived at their base camp around 3 p.m., where county search and rescue personnel helped escort them back toward the Clear Creek Trailhead. The hikers and rescuers returned without further incident.
After the rescue, the hikers acknowledged that they had relied too much on technology. According to the Forest Service’s account, they said, “We relied too much on AI instead of our own critical thinking.” The Siskiyou County Sheriff’s Office described the use of Gemini as a “critical misstep,” saying hikers had been advised to bring far less food and water than their group needed. However, officials stressed that the rescue was the result of a combination of problems and not a single error generated by the AI. The group continued beyond the recommended response time, descended after dark, lost their primary method of navigation, went off route, and did not have enough supplies to spend an unexpected night on the mountain. Authorities now advise climbers to contact the Mount Shasta Ranger Station before a trip, use established local information, carry multiple methods of navigation, including a paper map, periodically check their position, and prepare for unplanned overnight stays. The sheriff’s office specifically advises climbers who have not reached the summit by noon to turn around.
