The wreck of Ernest Shackletons Endurance, the ship at the heart of one of the worlds greatest survival stories, was discovered in the seas off Antarctica this week, more than a century after it was crushed by pack ice and sank.

This is by far the finest wooden shipwreck I have ever seen. It is upright, well proud of the seabed, intact, and in a brilliant state of preservation, marine archaeologist Mensun Bound, who served as the expeditions director of exploration, said in a news release . You can even see Endurance arced across the stern, directly below the taffrail. This is a milestone in polar history.
