1. South Geographic Pole 2. South Magnetic Pole (2007) 3. South Geomagnetic Pole[when?] 4. South Pole of InaccessibilityThe South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is one of the two points where the Earth's axis of rotation intersects its surface. It is the southernmost point on the surface of the Earth and lies on the opposite side of the Earth from the North Pole. Situated on the continent of Antarctica, it is the site of the United States Amundsen-Scott South Pole Station, which was established in 1956 and has been permanently staffed since that year. The Geographic South Pole should not be confused with the South Magnetic Pole, which though geographically nearby, is defined based on the Earth's magnetic field.
