The frozen land of Antarctica is not for ordinary people but Tom Crean was no ordinary man. When he was fifteen he ran away from home and joined the navy. His next step into the unknown took him to the Antarctic wilderness where he spent even more time than the famous explorers Scott or Shackleton. Going to the Antarctic 100 years ago was like going to Jupiter today. Explorers were cut off for years, 1000s of miles from the nearest outpost. Temperatures plunged far below zero. It was a struggle to survive. But Tom, the 'iron man', overcame the odds. He explored the unknown, crossed ice fields and wild oceans and courageously saved his friends from death. Edmund Hilary, the first to climb Everest, said: 'His courage, his determination, his loyalty to his leaders and team impressed me. He was a great man'. Mount Crean towers above Antarctica, named to honour this hero.
