As of Jan '06, the new Elevated South Pole Station was completed, replacing the old dome station which was being slowly buried by the ever increasing snow. Only a couple hundred people live at Pole during the summers, and the research consists of subjects like astrophysics, neutrino collecting, atmospherics, and other hard sciences. Pole doesn't ever get above about 7 degrees F, and is situated at 9300' on the polar plateau in the Great White Expanse.
A few times a season, someone in my dept goes to Pole to run a recreational overnight session for interested "polies" (there isn't much to do at Pole; a lot smaller and different than McMurdo).
