Dark Roasted Blend has lots of pictures of abandoned places in Antarctica, where the trouble to remove material is high and the low temperatures curb natural destruction. There's also a lot of strange facts about the continent.
While the South Pole and environs doesn’t have a permanent population, there are on average 2,500 people living there during the year -- approximately 4000 in summer and 1000 incredibly hardy ones in winter (source). While no complete necrologies exists for the Antarctic, at least 268 people have died there since humanity first decided it was a good place to visit. So if the ghosts divvie the work evenly, each one only has to haunt 9.68992 inhabitants.
