Officials say Harrison's cell phone company aided the search by sending an electronic query to his phone and getting the coordinates of his location. Harrison was unable to call for help because the cell signal was too weak.
Harrison is being treated at a Scranton hospital. Rescuers partly credit his survival to the fact he was dressed warmly. It was 18 degrees when searchers found him.
