500 days stranded on ice: Shackleton's expedition revisited


One hundred years after Ernest Shackleton's failed attempt to cross the Antarctic by ship, Australian adventurer Tim Jarvis set out to recreate the expedition and rescue mission which left members of Shackleton's team stranded for 500 days. In an interview with NBC's Ann Curry, Jarvis describes the journey's heart-rending moments. Jarvis's documentary, "Chasing Shackleton," premieres Jan. 8 on PBS.
