From the back of the box: Your plane has crashed in a remote region of the Sierra Nevada mountain range. Rescuee? Forget it. You're on your own. Your only chance of survival is to reach a distant ranger station. But first, you must determine your location using real navigation techniques, pack your supplies, and prepare for the dangers ahead. Your journey is made arduous by harsh weather, rough terrain, wild animals extreme physical demands, and your own lack of experience in sustaining yourself in the wilds. And your survival depends on your own common sense, quick wits, stamina, knowledge of survival techniques, and at least a little luck.
