Amundsen-Scott South Pole Station

 From the Station Guide:
"
Amundsen-Scott South Pole Station,
located at 90 degrees south latitude, sits
at an elevation of approximately 2,836
meters (9,306 ft), most of which is ice.
Because the Earth’s atmosphere is
thinner at the poles, the resulting average
“physiological altitude” is 3,223 m
(10,576 ft).

The average annual temperature at the
South Pole is -49.5° C (-57.1 °F), with a record low temperature of -82.8° C
(-117.0° F) in June 1982 and a record high of -13.6° C (+7.5° F) in December
1978.

The extremely dry environment limits annual snowfall. However, a relatively
constant wind speed of 5-15 knots accounts for the snow drifting common to
inland Antarctic stations. The surrounding terrain is virtually flat, except for
shallow waves of sastrugi (small snowdrifts)."
