Missing for a week on one of America’s most remote national parks, a 70-year-old solo hiker is found alive. Craig Berg was suffering from hypothermia but was "alive and alert" when rescuers reached him at Isle Royale National Park in Lake Superior after fellow backpackers spotted him and alerted authorities. Dramatic video shows a Coast Guard helicopter crew hoisting Berg from the remote island before flying him out for emergency medical evaluation. The rescue caps a massive multi-agency search involving K-9 teams, boats, drones, seaplanes and crews on foot after Berg failed to return from his extended hiking trip on Sept. 5. ▻
