South Pole

The Geographic South Pole is a unique location on Earth.

It is the southernmost point on the planet. This point sits in the Southern Hemisphere on the continent of Antarctica. It marks where the Earth's axis of rotation meets the surface. Scientists call this the True South Pole. This name helps distinguish it from the south magnetic pole. Because it is the axis, all lines of longitude converge here. This means the longitude at the pole is geometrically undefined. At this exact spot, every direction you look is North.

The geography of the pole is quite extreme. It sits on a featureless and barren icy plateau. This plateau is at a very high altitude above sea level. The area is a long way from the nearest open sea. The nearest sea is the Bay of Whales. The entire region is covered by a massive ice sheet. This ice is estimated to be very thick. Because of this thickness, the actual land surface is near sea level. The environment is windswept and very cold. It is one of the coldest climates on Earth.

The environment is constantly shifting due to the ice. The polar ice sheet moves at a steady rate. It moves toward the Weddell Sea. The movement is between 37 and 40 degrees west of grid north. This movement causes the geographic pole to shift position. Because of this, the marker must be moved every year. Staff members reposition the marker during a ceremony on New Year's Day. They also have to deal with accumulating snow. The snow does not melt at the pole. This means buildings can slowly become buried by snow over time.

Humans have a long history of exploring this frozen land. Several expeditions sighted Antarctica in 1820. In 1839, Charles Wilkes correctly identified it as a continent. Later, James Clark Ross tried to sail to the pole but failed. The race to the pole was a famous event. Roald Amundsen and his Norwegian party arrived first on 14 December 1911.

They named their camp Polheim. Robert Falcon Scott and his team reached the pole 34 days later.

Unfortunately, Scott and his companions died on their return trip. In 1929, Richard Evelyn Byrd became the first person to fly over the pole.

Modern activity at the pole is centered around research. The United States Amundsen–Scott South Pole Station is located there.

It was established in 1956 during the International Geophysical Year. The station has been permanently staffed since that year.

The station helps scientists study the Earth and space. There is also a Ceremonial South Pole nearby.

This area is used for photos and features many flags. It includes a metallic sphere on a short barber pole. It is located just a few meters from the actual geographic pole.

The light and weather at the pole follow a strange pattern. The seasons create very long periods of light or dark. During the winter from May to August, there is no sunlight. The pole is completely dark except for moonlight.

During the summer from October to February, the sun never sets. It stays above the horizon continuously. The sun appears to move from right to left. It stays low in the sky because of the Earth's 23.5 degree tilt. Much of the sunlight reflects off the white snow.

Many people have achieved incredible feats at the South Pole. In 1969, the first group of women reached the pole. In 1989, Arved Fuchs and Reinhold Messner traversed Antarctica via the pole. They used only skis and the wind for help. They did not use any animals or motors. Other explorers have set records for speed. In 2024, Vincent Colliard set a record for the fastest journey from the ocean. He reached the pole in about 22 days. These journeys show how much humans want to understand this remote place.
