Meanwhile, as the rest of the hikers continue down the mountain, Johnny picks up snatches of radio reports about an ozone emergency, resulting in a chemical imbalance in the forest. When Johnny alarms the other hikers, Shirley shouts at him and accidentally knocks his radio into a creek. When the hikers reach a spot where food has been left for them, they find that the boxes have been ripped apart by raiding animals and nothing is left. Jenson, challenging Steve's competence, says the group should stay there and wait for a helicopter to return, but Steve insists on pushing on down the mountain.
