From Aconcagua in South America to Mount Everest in Asia, from Kilimanjaro in Africa to Vinson Massif in Antarctica, from Mount McKinley in North America to Elbrus in Europe and Mount Kosciusko in Australia: no one had ever scaled all seven summits -- it would be a first, a feat that had eluded the world's best mountaineers.
Arguments rage back and forth over whether Mont Blanc or Elbrus in far southern Russia deserves this title, but, given a strict definition of the Asia-Europe boundary as the crest of the Caucasus, Elbrus is the king and therefore one of the famous Seven Summits.
