A Pole of Inaccessibility is a location on Earth that is extremely difficult to access. In the North, it is the point in the Arctic Ocean that is farthest from land, while in the Southern Hemisphere it is the point farthest from the Southern Ocean on Antarctica. In 1958, a Soviet team led by Yevgeny Tolstikov became the first people in history to reach the Southern Pole of Inaccessibility, which is 546 miles (878 kilometres) from the geographic South Pole. Temperatures at this location averages around – 73 degree F (–58 degrees C).
