one of the two points where the Earth's axis of rotation intersects its surface
Antarctica > South Pole

The Geographic South Pole is the point where the Earth's axis of rotation intersects the surface of the southern hemisphere, in the remote, bleak interior of Antarctica. The underlying land is close to sea-level but is covered by ice over 2.5 km thick, so the surface is at 2835 meters (9301 ft) altitude, on a flat, featureless plateau. The Pole was first reached by Amundsen in 1911, and the permanent US Amundsen-Scott South Pole Station has stood here since 1956.

Unless otherwise specified, references on these pages to "the Pole" mean this place. It shifts a few meters each year as the ice cap slowly moves, and there's also a "polar motion" as the earth's spin is slightly lopsided so the axis of rotation oscillates. See East Antarctica for the South Geomagnetic Pole and "Pole of Inaccessibility" (both some 800-900 km away across the plateau) and the South Magnetic Pole (way out to sea beyond Wilkes Land).

UnderstandEdit

 
The South Pole marker is replaced every year as the ice shifts

19th century explorers probed Antarctica's coasts but realized that the Pole lay over 1000 km inland in an intensely cold, uncharted region. The best route was from the Ross Sea, which ships could approach in summer. There you'd need to establish a base and lay supply caches along your return route, and camp over winter, to be ready to strike out for the Pole next spring and get back before the following winter overtook you. And how would you even know (and prove to the world) that you'd got there?

Several expeditions were forced back, the closest being Shackleton's Nimrod group of 1908 / 09 which reached within 180 km. This established that the interior, once you got beyond the Transantarctic Mountains, was a featureless high-altitude plateau. Roald Amundsen (1872-1928) was initially aiming for the North Pole, but this target was mired by contested claims of Peary and others to have reached it, and funding dried up. (Not until 1926 did Amundsen himself bring the first verified party to the North Pole, by airship.) He secretly switched focus to the South Pole and didn't even tell his crew until they'd left their last port-of-call in Madeira. They reached Antarctica in Jan 1911, camping on the edge of the Ross Sea ice shelf. They laid caches then in October set out with dog-hauled sleds along a straight line south, crossing the mountains by the Axel Heiberg Glacier, and reaching the Pole on 14 Dec. They returned safely to the coast in Jan 1912. Just as they were doing so, Scott's Terra Nova expedition belatedly reached the Pole, to find Amundsen's tents and the Norwegian flag fluttering there. That group of five did not survive their return north.

No one stepped foot on the Pole again until 1956, when a US Navy plane landed. Over the summer of 1956 / 57, the "International Geophysical Year", the US constructed a station which has been permanently staffed since. The next people to come overland, with limited air support, were Edmund Hillary and Vivian Fuchs, arriving separately in Jan 1958. The age of tourism began in 1987 with the opening of privately-run Patriot Hills airfield and camp, which in 2010 / 11 relocated to Union Glacier Camp, and this remains in use.

The climate at the South Pole is intensely cold, though it's not the coldest place on earth - that's in the vicinity of Vostok station at higher altitude. In December, mid summer, the Pole averages minus 28°C (minus 18°F), and in July this drops to minus 80°C (minus 112°F). (There are no "day-time highs" or "night-time lows", since in summer it's always day and in winter it's always night.) The Pole is also very dry, and indeed is classed as desert. It seldom catches the furious "katabatic" winds that scourge the coast. However, it doesn't take much breeze to kick up the drifting snow into a blizzard white-out that will disorient then bury anyone caught out in it.

Get inEdit

 
Tractors on the South Pole Traverse

By planeEdit

Flights come into the Jack F. Paulus Skiway, open in summer Oct-Feb. Only ski-planes can land here so the first leg of the journey (say, from Punta Arenas) is by conventional wheeled aircraft to one of the few Antarctic airfields that can receive them, there transferring to ski-plane. There may be a stopover of a couple of days at the transfer point to await a weather window to fly onward.

There are no scheduled commercial flights to the Pole. Staff come and go on government-sponsored flights. Tourists arrive on fly-stay packages, for prices that start from US$65,000 pp.

- a day trip to the South Pole or overnight stay;
- "Ski the Last Degree" where you're dropped off at 89oS and spend two weeks ski-trekking the rest of the way;
- from coast to Pole, 1170 km with over two months skiing for 8 hours a day, hauling a sled weighing 50-60 kg.
  • Icetrek is ostensibly a different company yet offers packages, departure dates and prices identical to ALE.
  • Northwest Passage offer similar packages, including a combi of "Last Degree" and climbing Mount Vinson.
  • PolarQuest are mostly a cruise operation but they offer 6-7 day trips by plane from Punta Arenas via Union Glacier to the Pole.
  • White Desert flies you here business-class, for double the price of the other very expensive operators. Guests fly from Capetown in business jets to Whichaway Camp in Queen Maud Land (think deep-freeze glamping) then on to the Pole or along the coast to admire the Emperor penguins.

By roadEdit

The South Pole Traverse (or Highway) is a 1600 km trail from McMurdo Station on the Ross Sea to the Pole. It's compacted snow with crevasses filled in and marked by flags. It can only be traveled by specialized tractors, hauling sleds with fuel and supplies. These aren't very nimble so the trail has to take a long swerve around the Transantarctic Mountains to come onto the plateau.

Ski treks from coast to Pole are partly along this route, but take short-cuts through the mountains to bring the distance below 1200 km.

Get aroundEdit

The area of interest is all within one km of the Pole along marked trails, so you get around on foot. Never leave these trails. There's simply nowhere else to go - the next nearest point of interest is Kunlun station over 1000 km away, and frankly not worth the walk. This is a featureless plateau where conditions can turn from sparkling daylight to howling blizzard in an instant. The wind whips up the snow into a white-out where you have no sense of where you're going, and your trail gets covered so you can't retrace your route.

See and DoEdit

 
The ceremonial South Pole

See Antarctica#See_and_Do for general suggestions. The most important thing to do here is come home safe.

  • The ceremonial South Pole is a metal sphere on a red and white pole, set within the flags of the signatories of the Antarctic Treaty. It makes a good photo but is about 300 meters from the true Pole. (Yes, to be specific it's 300 meters north.)
  • The Geographic South Pole is marked by a simpler rod. The ice here shifts 10 meters annually and the marker is moved each New Year's Day in a small ceremony. There are also the US and Norwegian flags and a sign bearing quotes from the journals of Amundsen and Scott. Circumnavigate the world by taking a couple of dozen steps around the Pole.
  • There have been three generations of station structures:
    • The Old Pole, the original wooden station, was built in 1956 and abandoned in 1975. It's now buried by drifting snow, and off-limits as unsafe.
    • The 1970s Geodesic Dome was dismantled in 2009 / 10 and its site soon became covered by snow.
    • The brown Elevated Station, built from 1999, is a modular structure on stilts to prevent snow from accumulating around it. Semicylindrical metal "arches" next to the dome serve as storage, power plant, and vehicle shop. They linked to the main station via a 6-story unheated metal tower generally known as the "beer can".
  • The Visitor Center is a grand name for a small tent.
  • Ask the staff for a tour of the station – though the answer is often "sorry".
  • Play Disc Golf - this is the version where you flip a disc towards a target basket, playing your disc from wherever it lands. But it's odd that no golf course designer has sought to lay out a traditional course here.
  • Send a letter home from the world's southernmost post office in the station.

BuyEdit

There is a small gift shop in the station, cash only.

EatEdit

Visitors are fed at the camp site, and can't access the station canteen.

DrinkEdit

  • There's no shortage of fresh ice, but unlocking the water requires fuel and a means of heating. That's not a problem at the polar station and camp, but on treks such as "Ski the Last Degree" these add weight, and lugging them raises a thirst.
  • As in any very cold climate, never drink alcohol until you are safely in shelter. It's notorious for generating a false glow of warmth and well-being while your core body temperature ebbs away.

SleepEdit

Tourist visitors are accommodated at the campsite 1 km from the station and Pole, using "Arctic Oven" tents.

Stay healthyEdit

All the health and safety advice for Antarctica generally applies to the Pole. The main local factor is that intense dry cold is combined with altitude, so you need to acclimatize. That's usually done by spending a night at a staging post such as Union Glacier. The UV is also stronger at this altitude.

Go nextEdit

You're tied to your package itinerary, so you must return north with them. They may have the option of side-trips from their Antarctic staging post, eg from Union Glacier to Mount Vinson, or from McMurdo to climb the active volcano Erebus.
