Century-old box of Shackleton expedition negatives discovered in Antarctica

The Antarctic Heritage Trust of New Zealand announced (PDF) that it had discovered a century-old box of photographic negatives from Captain Scott's last expedition base at Cape Evans, depicting Ernest Shackleton's 1914-1917 Ross Sea Party. The mouldy cellulose nitrate negs were among 10,000 artifacts recovered from Scott's Cape Evans hut, and were "clumped together." The negs were painstakingly restored and the photos have been published. They're damaged but remarkable, and no one knows who took them. (via /.)
