A 70-year-old Michigan man who vanished while navigating the remote wilderness of Isle Royale National Park has been located safe following an intensive multi-day search operation. Craig Berg, a resident of Royal Oak, was discovered alive and alert on the island on Saturday, bringing a successful conclusion to an anxious week of searching by emergency responders and family members.
The National Park Service confirmed the positive outcome, stating that Berg was encountered by fellow backpackers who were traveling through the island's backcountry. Park officials announced the development through an official update, expressing relief that the missing hiker had been found safe days after he initially failed to return home as scheduled.
Berg had traveled to the isolated island park in Lake Superior in late August to embark on a solo hiking excursion. According to park records and information shared by his family, he originally arrived on the island on August 27 with plans to hike along the Greenstone Trail, one of the central footpaths that runs across the length of the park.
Concerns for the hiker’s safety mounted sharply when he failed to board his scheduled ferry ride back to the mainland on Saturday, September 5. Because Isle Royale is situated far offshore in Lake Superior and is accessible almost exclusively by ferry or seaplane, missing a reserved departure immediately raised alarms with transportation staff and park personnel.
When Berg did not appear for his designated return trip, he was officially reported missing and unaccounted for, prompting park authorities to launch missing-person search protocols. His wife, Debbie Berg, told the Detroit Free Press earlier in the week that her husband's failure to catch the September 5 ferry led to immediate fears that he had run into trouble along the remote trail.
Following the initial missing person report, emergency coordinators rapidly assembled a comprehensive search and rescue operation to locate the senior hiker. Because Isle Royale features dense forests, rugged terrain, and isolated wilderness trails, search coordinators were tasked with managing complex logistical challenges across a vast and difficult search area.
Search teams focused their primary efforts along the Greenstone Trail corridor, which was the planned route Berg had set out to trek during his solo journey. Debbie Berg confirmed during the search that emergency teams were concentrating their manpower and resources in and around that specific trail area in hopes of discovering signs of his whereabouts.
The rescue mission expanded into a large-scale, multi-agency collaborative effort that brought together personnel, specialized equipment, and canine units from various jurisdictions across the Upper Midwest. Multiple state, federal, and local public safety agencies mobilized to provide both ground support and advanced technological surveillance.
Ground operations involved repeated and thorough foot patrols across trails and potential off-trail paths where a solo hiker might have lost their way or sustained an injury. To enhance ground search capabilities, specialized search dogs and handlers from Wisconsin’s No One Left Behind Canine Search and Rescue were brought in to assist with the operation.
In addition to the personnel sweeping the ground, search leaders utilized substantial aerial assets to examine the dense wilderness canopy from above. Minnesota State Patrol Aviation Resources participated in the mission by conducting overflights, while search teams also deployed aerial drones to survey steep ridges and hard-to-reach sections of the island.
Maritime and law enforcement agencies provided vital operational reinforcement throughout the search period. Key support came from the U.S. Coast Guard Station Portage in Michigan, working alongside tactical and search teams from the Michigan State Police Special Operations Division, the Michigan Department of Natural Resources, and deputies from the Keweenaw County Sheriff’s Office.
By Friday, nearly a full week after Berg had missed his scheduled ferry, search operations remained fully engaged across the island. Field crews, aviation teams, and drone operators continued systematic sweeps in an urgent effort to locate the hiker amid changing weather conditions in the Lake Superior region.
The prolonged search reached a breakthrough on Saturday, September 12, when other backpackers traversing the island unexpectedly came across Berg. According to the National Park Service, the 70-year-old was found conscious and alert, marking a fortunate ending to an ordeal that had left him stranded past his planned departure.
Following his rescue, Isle Royale National Park posted a public update on social media to notify the community that Berg had been safely accounted for. Park authorities noted that a full assessment remains underway, explaining that additional details regarding his time on the island and subsequent rescue will take time to fully investigate and share.
