They should probably check for any part of the surroundings for any thing that stands out (e.g: the copter) and set up a camp and go out for the day and come back to his camp untill he knew the land. Then look for people or anything that would seem like eople would have been there before if si track them and be saved... If not he'd keep on looking (while surviving by getting fire and stuff)

If he didn't find anything he'd then try to find a high place and scout for any thing that might be useful (for surviving or for getting back).
