Considering the small population of the continent, Antarctica has a lot of abandoned settlements. In such extremely low temperatures, it is much easier to leave structures and possessions behind than to take them with you when you leave. Harsh conditions also preserve what is left, since bacteria and mold that break down materials elsewhere on earth can't survive in Antarctica. Camps and settlements abandoned 100 years ago still sit, appearing just as they did when they were in use. The hut shown was left by Sir Ernest Shackleton in 1909.
