【阅读理解】On a September day in 1991, two Germans were climbing the mountains between Austria and Italy．High up on a mountain pass，they found the body of a man lying on the ice. At that height(10,499 feet，or 3,200 meters)，the ice is usually permanent，but 1991 had been an especially warm year．The mountain ice had melted more than usual and so the body had come to the surface．It was lying face downward. The skeleton(骨架)was in perfect condition, except for a wound in the head. There was still skin on the bones and the remains of some clothes．The hands were still holding the wooden handle of an ax and on the feet there were very simple leather and cloth boots． Nearby was a pair of gloves made of tree bark(树皮)and a holder for arrows.
What can be inferred from paragraph 2?
