U.S. Antarctic Program participants wave goodbye to the last flight to leave Amundsen-Scott South Pole Station before winter isolation. Between mid-February and mid-October there are no flights to/from the South Pole. Forty-nine people spent the 2011 winter at Pole.
An aerial view of Amundsen-Scott South Pole Station. The silver geodesic dome was dedicated in 1975 as the second station to be built at the South Pole. It provided wind shelter for smaller buildings under it. Decades of accumulating snow drift, and growing scientific population, resulted in the decision to build a new station, seen at right, still under construction when this photo was taken.
