The Coldest Journey is the name of the expedition that is attempting what is said to be the first ever attempt to cross the Antarctic during the winter. This feat is one of the last great polar challenges remaining to be accomplished. The expedition is expected to begin its trek on March 21, 2013 at Crown Bay in Queen Maud Land in Eastern Antarctica. The expedition plans to finish around September 21, 2013 at McMurdo Sound where they will remain until being picked up by a ship in February 2014.
