Bored Panda has a post about 100 year old negatives that were discovered frozen in Antarctica.  The negatives were discovered in a box during restoration work of an exploration hut, which was carried out by the Conservators of the New Zealand Antarctic Heritage Trust.  The box contained 22 never before seen cellulose nitrate negatives that were probably left in Captain Scott’s hut by Ernest Shackleton’s 1914-1917 Ross Sea Party.  The photos can be seen on the Antarctic Heritage Trust’s website.
