In October and November 1999, NOVA journeyed into ice-choked Antarctic waters and onto the shores of rugged Elephant and South Georgia Islands as we followed in the footsteps of Sir Ernest Shackleton. This legendary explorer's 1914-1916 Endurance expedition is one of the greatest survival stories of all time. Then, in April 2000, we returned to document Shackleton's final trial—the crossing of South Georgia—by three of the world's most distinguished mountaineers, Reinhold Messner, Conrad Anker and Stephen Venables.
