The term describes a geographic construct, not an actual physical phenomenon. Subject to varying definitions, it is of interest mostly to explorers.
The southern pole of inaccessibility is the point on the Antarctic continent most distant from the Southern Ocean. The southern pole of inaccessibility is far more remote and difficult to reach than the geographic South Pole.
On 14 December 1958, the 3rd Soviet Antarctic Expedition for International Geophysical Year research work, led by Yevgeny Tolstikov, established the temporary Pole of Inaccessibility Station at 82°06″S 54°58″E. A second Russian team returned there in 1967.
Today, a building still remains at this location, marked by a bust of Vladimir Lenin that faces towards Moscow, and protected as a historical site. Inside the building, there is a golden visitors' book for those who make it to the site to sign.
