History of Everest

Mt. Everest is the tallest mountain above sea level at 29,029 feet.  In 1856, the Great Trigonometric Survey of British India created the first published height of Everest.  This peak was known as Peak XV at 29,002 feet above sea level.  In 1865, Everest was given its official English name by the Royal Geographical Society.  There were also very many attempts to climb Everest.  In 1885, Clinton Thomas Dent said that climbing Everest was possible.  He stated this in his book he wrote called Above the Snow Line.  The first ever attempt to climb Everest was by George Mallery in 1921.
