 Police in Peru have found the preserved body of an American mountaineer who disappeared more than 22 years ago. William Stamfel, who was 59, was climbing the snow-capped Mount Huascaran in western Peru when an avalanche buried his climbing party. Rescuers were unable to locate them at the time. The police say Mr Stamfel's body had been preserved by the cold and was exposed after an ice melt was brought about by climate change.
