A shocking story of brotherly betrayal that gripped the world of mountaineering for over 50 years has been put to rest after the discovery of a climber's boot previously entombed in a Himalayan glacier.
The boot, belonging to Geunther Messner, a young Italian climber who died in 1970 on the slopes of Naga Parbat in Pakistan, backs up his brother's story that he had been swept away in an avalanche.
Geunther and his brother Reinhold Messner, who went on to become of the world's most famous climbers, had been trying to climb the 26,660ft mountain when tragedy struck.
