A 36-year-old woman taking part in a YouTube-filmed "survival challenge" was found nearly 18 hours after she left her designated base camp in Michigan's Pigeon River State Forest, state police said.

The Michigan State Police helicopter Trooper 6 located the woman in a swampy clearing at 10:40 a.m. Saturday after a multi-agency search. The moment was captured on the helicopter’s thermal camera and posted on social media by the MSP 7th District. In the video, the pilot can be heard saying, "Command Six, we definitely got her."

According to the Otsego County Sheriff's Office, the woman, who is from California, left the camp around 5 p.m. Friday to look for water and did not return. Contest organizers conducted an initial search, but authorities were not notified until about 5 a.m. Saturday, sheriff’s officials said. The 911 call triggered a coordinated response that included Michigan State Police troopers from the Gaylord Post, canine teams and local firefighters.

Searchers faced difficult conditions. Much of the state forest remains littered with downed trees and tangled branches from a severe ice storm earlier this year, officials said, complicating ground searches and pushing crews to deploy aerial assets. Weather overnight was cold and rainy, and the forest is known for bears and wolves and generally punishing terrain.

Trooper 6’s thermal imaging allowed the helicopter crew to direct ground teams and canine handlers to the woman’s exact location. She was visibly waving at the helicopter in the footage and was able to walk out under her own power, authorities said. Emergency medical personnel evaluated her on scene and released her with no serious injuries. The MSP 7th District posted, "Great work by all first responders on scene!"

Officials have not released the woman’s name or provided details about the YouTube challenge, including whether permits were obtained or what safety protocols were in place. The hosts of the contest have not been publicly identified.

The incident drew immediate attention online and from rescue professionals, who have in recent years warned about increasing risks tied to endurance stunts and unsupervised internet challenges that send participants into hazardous, unregulated environments. Social media reactions ranged from relief at the successful rescue to criticism of the event’s organizers and calls for them to be held financially responsible for emergency response costs. "It's not a survival challenge if search and rescue are called. It's just a 'don't get lost' challenge," one user wrote.

Authorities said the woman is expected to make a full recovery and that the outcome could have been far worse without the helicopter’s thermal imaging. The case remains under review by local officials, who have not announced any enforcement actions or investigations related to the challenge or its organizers.
