In 1915 Ernest Shackleton’s ship, Endurance, sank off the coast of Antarctica, stranding the crew on drifting sea ice. Shackleton’s desperate rescue mission saved all 28 men.

National Geographic photographer Esther Horvath was there, and recounts the moment when the ship was located 10,000 feet beneath the polar ice.
