The fastest unsupported walking journey to the Geographic South Pole from the ocean is 47 days and was set in 1999 by explorers Tim Jarvis and Peter Treseder，who hauled 200 kg sleds containing food and cooking fuel. At present，Antarctica is located over the South Pole，although this has not been the case for all of Earth's history because of continental drift.The Amundsen­Scott South Pole Station was established during the International Geophysical Year in 1958 and is permanently staffed by research and support personnel.
