North Pole
Northernmost point on Earth, located in the Arctic Ocean.
The North Pole, sometimes called the Geographic or Terrestrial North Pole, marks the spot in the Northern Hemisphere where the planet’s rotational axis meets the surface. It is the farthest north point on Earth, directly opposite the South Pole, and sits at 90° North latitude. Unlike the South Pole, which rests on a continent, the North Pole lies in the middle of the Arctic Ocean, surrounded by water that is almost always covered in drifting sea ice.
Because all lines of longitude converge here, the North Pole has no fixed longitude—any value works—and all directions from it point south. It also has no assigned time zone, so any time can be used locally. On tight latitude circles, going counterclockwise is east and clockwise is west. The nearest land is Kaffeklubben Island, off Greenland’s north coast, about 700 kilometers away, though some semi-permanent gravel banks are slightly closer. The closest permanently inhabited place is Alert, on Canada’s Ellesmere Island, 817 kilometers from the Pole.
The sea depth at the North Pole has been measured twice: at 4,261 meters by a Russian submersible in 2007, and at 4,087 meters by the USS *Nautilus* in 1958. This depth makes a permanent station impractical, unlike at the South Pole. Still, the Soviet Union and later Russia have operated manned drifting stations on a mostly annual basis since 1937, some passing over or very near the Pole. Since 2002, a private Russian base called Barneo has been set up near the Pole each year for a few weeks in early spring. Studies in the 2000s predicted that the North Pole could become seasonally ice-free due to Arctic ice shrinkage, with estimates ranging from 2016 to the late 21st century or later.
Attempts to reach the North Pole started in the late 1800s, with the “Farthest North” record broken many times. The first undisputed arrival was by the airship *Norge* in 1926, which flew over the area with 16 men, including leader Roald Amundsen. Three earlier expeditions—by Frederick Cook (1908, land), Robert Peary (1909, land), and Richard E. Byrd (1926, aerial)—were once accepted but later doubted after analysis of their data. The first verified people to reach the Pole on foot were a 24-man Soviet team in 1948, part of Aleksandr Kuznetsov’s Sever-2 expedition; they flew close, then walked the final stretch. The first complete land expedition to reach the Pole on foot was in 1968 by Ralph Plaisted, Walt Pederson, Gerry Pitzl, and Jean-Luc Bombardier, using snowmobiles and air support.
The Earth’s axis—and thus the North Pole’s position—was long thought fixed until the 18th century, when mathematician Leonhard Euler predicted a slight wobble. Around 1900, astronomers noticed a small “variation of latitude” from star observations, partly due to the Pole wandering a few meters across the surface. This wandering has several periodic and irregular components. One component, with a period of about 435 days, matches Euler’s prediction and is called the Chandler wobble. The exact intersection of the axis and surface at any moment is the “instantaneous pole,” but the wobble prevents using it as a fixed definition when meter-scale precision is needed. To tie Earth coordinates to stable landforms, the International Earth Rotation and Reference Systems Service and the International Astronomical Union created the International Terrestrial Reference System, though plate tectonics and isostasy mean no system is perfectly fixed.
In the 16th century, many believed the North Pole lay in an open sea, called the Polynya or Open Polar Sea, hoping for a passage through ice at favorable times. Expeditions often used whaling ships. One of the earliest explicit attempts to reach the Pole was by British naval officer William Edward Parry in 1827, who reached 82°45′ North. The 1871 *Polaris* expedition, a U.S. attempt led by Charles Francis Hall, ended in disaster. Another British Royal Navy try, part of the British Arctic Expedition under Commander Albert H. Markham, reached a record 83°20'26" North in May 1876 before turning back. An 1879–1881 expedition by U.S. Navy officer George W. De Long ended tragically when the USS *Jeannette* was crushed by ice; over half the crew, including De Long, died. In April 1895, Norwegian explorers Fridtjof Nansen and Hjalmar Johansen skied for the Pole after leaving Nansen’s icebound ship *Fram*, reaching 86°14′ North.

Lore & Background
The North Pole is the northernmost point on Earth, located in the middle of the Arctic Ocean on sea ice that is constantly shifting. Unlike the South Pole, which sits on a continental landmass, the North Pole lies over deep water, making a permanent station impractical. The sea ice at the Pole is typically multi-year ice, and pressure ridges can form between ice floes. The nearest land is Kaffeklubben Island, off Greenland’s northern coast, while the closest permanently inhabited place is Alert, Canada, on Ellesmere Island. Because all lines of longitude converge at the Pole, its longitude is undefined, and no time zone is assigned; all directions from the Pole are south. The Earth’s axis of rotation, which defines the Pole’s position, is not perfectly fixed but undergoes a slight wobble, known as the Chandler wobble, causing the instantaneous pole to wander by a few meters. This variation is accounted for by the International Terrestrial Reference System. The first undisputed arrival at the Pole was an aerial overflight by the airship Norge in 1926, led by Roald Amundsen. Earlier claims by Frederick Cook, Robert Peary, and Richard Byrd are now doubted. The first verified individuals to reach the Pole on foot were a Soviet party in 1948, and the first complete land expedition using snowmobiles arrived in 1968. Since 1937, the Soviet Union and later Russia have operated annual drifting stations near the Pole, and since 2002 a private Russian base called Barneo has been established each spring.
Reader's Guide
The North Pole holds significance as a geographic and symbolic endpoint of Earth's axis. Its location in the shifting sea ice of the Arctic Ocean makes permanent habitation impractical, unlike the South Pole. Studies in the 2000s predicted possible seasonal ice-free conditions due to Arctic ice shrinkage. The Pole's precise definition is complicated by the Chandler wobble, a periodic variation in the Earth's axis of rotation, requiring the International Terrestrial Reference System for accurate coordinate tying.

Origins and Causes of Phantom Islands
Phantom islands typically trace their existence to the age of early maritime exploration, when sailors charted unknown waters with limited instruments and unreliable observations. A single misread of the horizon, a fleeting ice formation mistaken for solid ground, or an unverified rumor passed between crews could all seed a fictional landmass onto a chart. Navigational errors, mistaken observations of fog banks or pumice rafts, and even deliberate fabrication by cartographers all contributed to the phenomenon. In some cases, what sailors genuinely saw was something real but misidentified—breakers, icebergs, or superior mirages like the one that may have produced New South Greenland in the Weddell Sea in 1823. Other times, the error was purely cartographic: Pepys Island was simply a misidentification of the Falkland Islands, while the Baja California Peninsula and Banks Peninsula appeared as separate islands on early maps before their mainland connections were confirmed. Isle Phelipeaux, a phantom duplicate of Isle Royale in Lake Superior, persisted on explorers' maps for years and even served as a border landmark between the United States and what would become Canada before surveyors proved it was never there.
The Long Life of False Landmarks
Dougherty Island exemplifies how a phantom can persist across generations. Captain Daniel Dougherty of the Irish whaler James Stewart first reported sighting it in 1841, describing a snow-covered landmass five to six miles long with a high bluff to the northeast. Captain Keates of the Louise confirmed it in 1860, and Captain Stannard of the Cingalese added another sighting in 1886, each time with slightly shifted coordinates. Yet the island stubbornly remained on charts until at least 1934. Emerald Island followed a similar arc: first sighted by the British sealing ship Emerald under Captain William Elliot in December 1821, it was presumed to be a small mountainous island. The 1840 United States Exploring Expedition found nothing, a 1909 search by the Nimrod turned up nothing, and yet it still appeared in a 1987 American Express desk calendar atlas. Sandy Island, charted in the Coral Sea from the late 19th century, was undiscovered in the 1970s but lingered in digital mapping datasets until its non-existence was re-confirmed in 2012.
Phantom Versus Lost: A Spectrum of Error
A phantom island occupies a distinct conceptual space from a lost land. Lost lands are those believed to have once existed but were subsequently swallowed by the sea or destroyed by geological forces. A phantom island, by contrast, is claimed to exist in the present moment yet is later revealed never to have existed at all—or, in the case of the Island of California, never to have been an island in the first place. The spectrum of phantom origins is broad. Some may have been purely mythical, such as the Isle of Demons near Newfoundland, possibly rooted in local legends of a haunted island, or the far-northern Thule reported by the 4th-century BC Greek explorer Pytheas, whose true location remains debated among Shetland, Iceland, Scandinavia, or nonexistence. Hy-Brasil, depicted west of Ireland, was similarly fanciful. Others arose from genuine but misread geography, while still others—like Thompson Island or Bermeja—may have been real islands later obliterated by volcanic explosions, earthquakes, or submarine landslides. Pactolus Bank, visited by Sir Francis Drake in 1578, might represent a low-lying sand bank that simply sank below the waterline.
Cultural Echoes and Cartographic Stubbornness
The phantom island has left a lasting mark on literature and cartographic practice alike. Herman Melville wove the phenomenon into Moby-Dick, where the narrator reflects on how a dead sperm whale's carcass, set adrift after being processed, could be mistaken from a distance for a shoal or reef. In his vivid passage, a blundering discovery-vessel spots the white mass floating in the sun and, with trembling fingers, logs it as dangerous breakers, causing ships to shun the location for years. This literary nod captures the broader truth that phantom islands often begin as a single moment of misperception amplified by subsequent repetition. Cartographers themselves sometimes played a role, deliberately inserting invented features into maps either to defraud or to trap plagiarists. The persistence of these fictions is remarkable: features that were undiscovered decades or even centuries earlier continued to appear in official mapping data well into the 21st century, as Sandy Island's survival in digital datasets until 2012 demonstrates. The phantom island thus stands as a testament to how easily a single error can calcify into accepted geography.
Frequently Asked Questions
What is the North Pole?
It is the precise spot on Earth's surface where the planet's rotational axis intersects the ground in the Northern Hemisphere, representing the absolute northernmost coordinate at 90° latitude.
Where is the North Pole physically located?
Rather than resting on solid ground, it sits in the open Arctic Ocean atop a vast sheet of sea ice that is almost permanently frozen but constantly shifting and breaking apart.
Who first reached the North Pole?
The first widely accepted crossing came in 1926 when Roald Amundsen and Umberto Nobile flew over the region in the airship Norge, while the first verified on-foot visit was made by a Soviet team in 1948 who walked a short distance after landing by aircraft.
How does the North Pole differ from the South Pole?
The South Pole is anchored to the Antarctic continent, a fixed landmass, whereas the North Pole floats on ever-moving ocean ice, so the exact geographic point drifts slightly as the ice pack shifts.
Why was the North Pole so difficult to reach?
Because the pole is embedded in a featureless expanse of Arctic sea ice with no landmarks, no landfall for navigation, and a constantly shifting footing that could break apart beneath an expedition at any moment.
