Bill searched the terrain and saw another canyon leading to the south. He turned his plane into that and found that it was much narrower than any of the others that he had flown through. The fog seemed to hang higher. Perhaps he might get through. The air became much rougher and with the rough air came a slight rain. Bill flew through the rain and found that the floor of the valley was gradually getting closer to the plane. He could not climb any higher, as the clouds were just above his top wing. In fact at times he flew through the lower patches of mist.
