100-year-old negatives have been discovered in Antarctic. They where in a small box of 22 exposed but unprocessed photographic negatives, frozen in a solid block of ice for nearly one hundred years. The Box was  one of the many supply depots Robert Falcon Scott established for his doomed Terre Nova Expedition to the South Pole (1910-1913).
The hut was used next by the Ross Sea Party of Sir Ernest Shackleton's 1914-1917 Imperial Trans-Antarctic Expedition. It is believed that this party left the undeveloped negatives.
What an incredible story!
