The Plain of Jars is not an archaeological void: burials, quarries and dating evidence support mortuary use over a long period. The exact sequence, social meaning and identity of its builders remain active research questions.
Xiengkhouang Plateau near Phonsavan; representative Site 1 pin / explainedA classic strange-archaeology case in which a plausible object became a magnet for much larger claims than the evidence supports.
Near Baghdad / disputedThe Nazca Lines are extraordinary landscape works, but careful archaeology explains them through human labour, ritual geography and desert preservation.
Nazca Desert / explainedThe Antikythera Mechanism is genuinely astonishing, but its lesson is ancient technical skill, not a shortcut to fringe claims.
Antikythera shipwreck; National Archaeological Museum, Athens / explainedRoman dodecahedra are genuine, technically demanding provincial objects. Their variable sizes, scattered contexts and missing textual record keep practical and ritual explanations provisional.
Norton Disney, Lincolnshire; exact excavation-context pin / uncertainIn the late 12th century, two chroniclers recorded a story about green-skinned children found near Woolpit. The shared core is old; its meaning and literal history remain uncertain.
Woolpit, Suffolk; representative village pin / folkloreNan Madol remains archaeologically challenging, but its builders and broad chronology are not unknowable. Local oral histories, settlement evidence and scientific dating converge on Pohnpeian construction and Saudeleur power.
Temwen Island reef, Pohnpei / explainedThe Shroud of Turin is valuable to the archive because it forces every question about provenance, authentication and interpretation into the same room.
Turin, Italy / disputedThe Voynich Manuscript is a real medieval codex filled with undeciphered writing, strange plants and diagrams that keep attracting scholars, codebreakers and dreamers.
Beinecke Rare Book and Manuscript Library, Yale University / uncertainThe princes probably died after entering the Tower of London, and Richard III had custody and benefited politically. The surviving evidence supports suspicion, not a proved murder method or uniquely identified culprit.
Tower of London, England / disputedWill-o’-the-wisp is a folklore category attached to real and misperceived lights, not one proven mechanism. New chemistry offers a plausible methane-ignition route while direct modern field measurements remain limited.
European wetlands; representative East Anglia fen pin / uncertainIn Strasbourg, reports of compulsive dancing became one of history's strangest examples of body, belief, stress and record colliding.
Strasbourg, Alsace / uncertainBlack Shuck endures because it is a black-dog legend that can stand for warning, death, landscape and local memory at the same time.
Blickling Hall and East Anglia / folkloreThe Roanoke disappearance endures because one carved word, missing people and colonial uncertainty leave room for both evidence and imagination.
Roanoke Island, North Carolina / uncertainThe Tedworth disturbances are preserved through partisan Restoration-era accounts rather than a neutral investigation. Noises were reported, but fraud, household performance and supernatural interpretation cannot now be separated decisively.
Tidworth, Wiltshire; representative historic pin / disputedThe Salem witch trials remain a severe lesson in how fear, theology, testimony and legal process can combine into a lethal accusation system.
Salem Village and Salem Town, Massachusetts / explainedEpworth’s “Old Jeffrey” is unusually well documented through Wesley family correspondence, but the accounts remain household testimony copied and published later, with no independent test of the noises.
The Old Rectory, Epworth, Lincolnshire; representative site pin / uncertainMary Toft’s rabbit-birth claims were a documented medical hoax. The case reveals unequal power, weak observation and the speed with which professional authority can magnify a spectacle.
Godalming, Surrey; representative town pin / hoaxThe Cock Lane Ghost became a public test of spirit claims, murder accusations and experimental controls. Contemporary investigators ultimately exposed deliberate production of the knocks.
Cock Lane, Smithfield, London; representative street pin / hoaxLethal attacks in Gévaudan prompted royal hunts and national coverage from 1764 to 1767. The deaths are historical; whether one unusual animal caused them is disputed.
Gévaudan attack region; representative pin at Saugues / disputedThe Tatzelwurm is a durable Alpine animal tradition assembled from inconsistent sightings, regional names and later illustration. Familiar wildlife and folklore explain more than an undiscovered species.
Aare Gorge, Bernese Oberland; representative Alpine folklore pin / folkloreChangeling lore is a family of supernatural explanations preserved across Europe. Folklore archives reveal its variety, while historical cases show the danger of treating a metaphor or diagnosis as a literal replacement.
Ireland; representative National Folklore Collection context pin / folkloreThe Hammersmith Ghost is historically established as a rumour with lethal consequences, not as a verified haunting. Trial evidence documents mistaken identification, public fear and a lasting legal problem.
Black Lion Lane, Hammersmith, London; approximate historic location / explainedA brewery vat rupture released a destructive flood of porter into St Giles on 17 October 1814. Contemporary reports and the inquest document eight deaths and an accidental verdict.
St Giles, London; former Horse Shoe Brewery area / explainedThe Bell Witch story is one of America's most durable haunting legends, but its power comes from later storytelling as much as any recoverable event.
Adams, Robertson County, Tennessee / folkloreKaspar Hauser was a real unidentified youth whose changing story attracted patrons and suspicion. Modern mitochondrial DNA excludes the House of Baden maternal line; it does not reveal his parents or fully resolve his fatal wound.
Unschlittplatz, Nuremberg, Bavaria; representative appearance location / disputedWillington Mill has an unusually long documentary trail, including Joseph Procter’s journal. It establishes repeated family reports, not a verified supernatural agent, and leaves ordinary noise, performance and memory in competition.
Willington Mill, Northumberland / uncertainThe Wild Hunt is best understood as a scholarly and popular umbrella for varied regional traditions, not one unchanged pagan myth transmitted intact across Europe.
Northern and western Europe; representative central-European pin / folkloreIn 1835, newspaper readers met moon forests, lunar animals and winged people in a celebrated lesson about media, science and appetite.
New York / hoaxThe Feejee Mermaid became an object lesson in showmanship because the hoax was never just the object; it was the lecture around it.
New York and international exhibition circuits / hoaxThe Franklin expedition was destroyed by a compound Arctic disaster rather than a single mysterious event. Inuit knowledge and archaeology have recovered its ships, while the exact movements and deaths of the crews remain incomplete.
King William Island, Nunavut; approximate Victory Point record location / uncertainThe Fox sisters' spirit raps helped launch modern Spiritualism, then became a lesson in performance, grief, confession and belief that survives exposure.
Hydesville and Rochester, New York / hoaxSelkie stories are living folklore rather than zoological reports. Their variants preserve island relationships with seals and the sea, while modern retellings increasingly examine consent in the stolen-skin marriage plot.
Orkney and Shetland; representative northern isles pin / folkloreAfter a snowy night in February 1855, residents around the Exe estuary reported small, regular tracks in unlikely places. The reports preserve a genuine local mystery, not proof of a single supernatural traveller.
Exe estuary and south Devon; representative pin at Exmouth / uncertainBorley Rectory became a benchmark haunted-house case because witness claims, press attention, Harry Price's investigations and later criticism all gathered around one vanished building.
Borley, Essex / disputedThe Cardiff Giant was a carved gypsum fake sold as a petrified ancient man, and it remains one of the cleanest lessons in spectacle, profit and belief.
Cardiff, New York / hoaxThe famous 1872 maritime mystery is less a ghost story than a stubborn problem of evidence, weather, cargo and missing people.
North Atlantic, between the Azores and Portugal / uncertainGiant squid demonstrate that extraordinary animals can be real while legendary behaviour remains unsupported. Specimens, anatomy, DNA and live imaging establish Architeuthis without validating ship-attacking kraken tales.
North Atlantic and global deep ocean; representative Newfoundland pin / explainedThe Kentucky Meat Shower was a documented fall of animal tissue, not weather creating meat. Conflicting identifications and absent surviving evidence leave the source probable rather than certain.
Olympia Springs, Bath County, Kentucky; approximate pin / uncertainThe Amherst case rests chiefly on Walter Hubbell’s participant narrative of noises, fires, messages and moving objects around Esther Cox. Some incidents had witnesses; controls were poor.
Amherst, Nova Scotia; representative town pin / disputedThe Marfa Lights combine a modern roadside observation problem with older local folklore. Headlights and atmospheric effects explain much of the repeatable display without resolving every anecdote.
Mitchell Flat east of Marfa, Texas; representative viewing-area pin / uncertainA haunted-house legend built from grief, construction history, architectural oddity and a very persistent public appetite for story.
San Jose, California / folkloreThe 1896–97 mystery-airship wave mixed ambiguous lights, invention fever, jokes and newspaper storytelling. No verified machine accounts for the national narrative.
Sacramento, California; representative pin for a nationwide newspaper wave / folkloreThe Saint Augustine Monster was a real stranded carcass whose decayed form misled early observers. Preserved samples support degraded whale tissue, not a giant octopus.
Anastasia Island near St Augustine, Florida; approximate discovery-area pin / explainedScientifically examined crystal skulls do not support claims of ancient or paranormal origin. Tool marks, quartz provenance and sales records place prominent examples in the modern era.
British Museum, London; exact collection-context pin / explainedThe Greenbrier Ghost story grew around the 1897 death of Zona Shue and the conviction of her husband. Folklore influenced suspicion, while physical findings supported the prosecution.
Greenbrier County, West Virginia; representative county pin / folkloreThe Kensington Runestone is a real carved object with disputed origins. Its language, runes and discovery context favour a nineteenth-century creation, while the identity and precise motive of its maker remain unresolved.
Near Kensington, Douglas County, Minnesota; representative find-area pin / disputedThree lighthouse keepers disappeared from Eilean Mor in 1900, leaving a mystery where official records point toward sea, weather and working risk rather than fantasy.
Eilean Mor, Flannan Isles / uncertainSkin, skull and later living observations established the okapi as a giraffid. The evidence was gathered through Indigenous expertise within a colonial system that long credited outsiders more than local knowledge.
Ituri Forest; representative Okapi Wildlife Reserve pin / explainedCharlotte Moberly and Eleanor Jourdain described an uncanny walk at Versailles in 1901. Their early notes and later research document a developing interpretation, not independent proof of a time slip.
Petit Trianon, Versailles / disputedReports from Van Meter told of a horned, winged figure and a mine confrontation in September 1903. Period newspapers preserve the story, but independent corroboration is difficult to establish.
Van Meter, Dallas County, Iowa; representative town pin / folkloreN-rays were reported by respected physicists using faint visual changes near the threshold of perception. Failed replication and uncontrolled tests showed that the proposed radiation was not established.
University of Nancy; representative pin / explainedThe Phaistos Disc is a genuine-looking Minoan artefact with 45 sign types and no adequate parallel text. Its script, language and purpose remain undeciphered.
Palace of Phaistos, Crete / uncertainA 1908 blast over Siberia flattened forest without leaving a classic impact crater, making Tunguska a cornerstone case in anomaly, science and myth.
Podkamennaya Tunguska River region, Siberia / explainedThe Jersey Devil shows how regional folklore, landscape and newspaper appetite can turn a local creature story into a durable public monster.
New Jersey Pine Barrens / folkloreThe Hope Diamond is real, spectacular and historically traceable; the curse attached to it is better read as media folklore and gem-market theatre.
Smithsonian National Museum of Natural History, Washington, D.C. / folkloreBlood Falls is visually uncanny but scientifically explained. Its colour comes from iron oxidation, while its isolated salty ecosystem remains valuable for studying life beneath ice.
Taylor Glacier, McMurdo Dry Valleys / explainedPiltdown Man fooled parts of the scientific world for decades because forged evidence appeared to fit a story people were ready to hear.
Piltdown, Sussex / hoaxThe Fátima crowd event is historically documented, while its cause and religious meaning remain disputed. Testimony, expectation, optics and weather must be kept distinct.
Cova da Iria, Fátima; exact public site pin / disputedTwo Yorkshire cousins, a camera and a set of fairy photographs became one of the most instructive image hoaxes of the twentieth century.
Cottingley, West Yorkshire / hoaxThe disappearance of USS Cyclops is a major United States Navy loss without a recovered wreck. Structural, loading, weather and wartime explanations remain constrained by missing evidence.
Atlantic route from Barbados to Baltimore; representative departure pin / uncertainThe Carroll A. Deering was found abandoned on Diamond Shoals in January 1921. Missing boats, papers and crew suggested an organised departure, but its cause remains unknown.
Diamond Shoals off Cape Hatteras, North Carolina / uncertainThe Hinterkaifeck victims were found on 4 April 1922 and probably killed on 31 March. Official files establish the crime and extensive inquiry, not the identity or movements of the murderer.
Former Hinterkaifeck farm near Gröbern, Bavaria; approximate pin / uncertainThe Ape Canyon incident became a foundation story in Pacific Northwest Bigfoot lore. The miners were identifiable, but the creatures and attack survive through testimony and press retelling.
Ape Canyon, Mount St Helens; approximate historic mining-area pin / folkloreThe expedition disappeared after leaving Dead Horse Camp, most plausibly through accident, illness, starvation or violence. Archaeology validates complex pre-Columbian Amazon settlements, not Fawcett’s particular Z or any theory of his fate.
Upper Xingu region, Mato Grosso; representative Dead Horse Camp area pin / uncertainThe crew abandoned Baychimo after it vanished during a 1931 blizzard. The steel steamer survived and was repeatedly sighted or boarded; its final resting place remains unknown.
Beaufort Sea near Point Barrow; representative abandonment-area pin / uncertainFrom 1931, the Irving family said a talking animal inhabited their Isle of Man farmhouse. Notes, interviews and samples survive, but the claimed mongoose was never independently established.
Cashen’s Gap near Dalby, Isle of Man; representative pin / disputedThe famous Loch Ness image became a visual shorthand for lake monsters, then a lesson in scale, cropping and media appetite.
Loch Ness, Scotland / hoaxThe thylacine is historically real and well documented, but persistence is a separate claim. Habitat, witness error and search limits leave room for uncertainty while the continuing absence of diagnostic evidence weighs against survival.
Tasmania; representative central-western pin / uncertainThe Brown Lady became famous because a single staircase image turned a house tradition into a visual ghost story that critics could never quite put back in the box.
Raynham Hall, Norfolk / disputedThe banshee is a documented and diverse body of folklore. Recorded experiences establish belief and narrative practice, not a supernatural prediction, while coincidence and memory help attach cries to later deaths.
Ireland; representative Galway pin / folkloreThe surviving radio and search record most directly supports fuel exhaustion and a sea crash near Howland. Castaway and capture theories remain possible narratives but lack confirmed physical evidence linking Earhart to another location.
Howland Island vicinity; intended destination and representative search-area pin / uncertainThe 1938 coelacanth was a genuine zoological surprise. Its rediscovery demonstrates gaps in sampling while modern genetics corrects the misleading idea of a species frozen in time.
East London harbour, Eastern Cape; representative discovery-context pin / explainedA classic media panic case showing how a drama, late tuning and newspaper repetition turned a radio play into a durable legend.
United States / disputedOurang Medan is a maritime legend built through changing newspaper and magazine retellings. No verified ship registration, crew list, wreck or rescue record anchors the event.
Strait of Malacca; representative pin from later versions / folkloreVanishing-hitchhiker stories are documented folklore rather than one verified recurring event. Their changing details, local authentication and older supernatural motifs reveal how a modern legend acquires credibility.
Archer Avenue, Chicago; representative pin for the Resurrection Mary variant / folkloreIn February 1942, Los Angeles saw searchlights, anti-aircraft fire and rumours of enemy aircraft in a case where fear, weather and uncertainty lit up the sky.
Los Angeles, California / disputedThe Mad Gasser episode combined sincere symptoms, ordinary odours, rumour and alarming press coverage. A coordinated chemical assailant was never established.
Mattoon, Illinois; representative town pin / explainedA Christmas-night fire destroyed the Sodder home in 1945. Five children were missing afterward; uncertain recovery work and disputed clues left death in the fire and removal from the house unresolved.
Fayetteville, West Virginia; representative town pin / uncertainThe Bennington Triangle is less a single event than a regional pattern built from disappearances, local lore and the human need to connect coincidences.
Southwestern Vermont / uncertainRoswell began with recovered debris and a mistaken military press release. Project Mogul explains the material record; later alien-body narratives arose through retrospective testimony.
Ranch country northwest of Roswell, New Mexico; representative pin / explainedKenneth Arnold’s 1947 report helped launch the modern flying-saucer era. His observation was sincere and carefully timed, but distance and object identity were never independently secured.
Cascade Range near Mount Rainier, Washington; representative pin / uncertainDNA from hairs embedded in the death mask produced a strong genealogical identification announced in 2022. South Australian authorities have continued their own review, so identity confidence should not be confused with an official cause-of-death finding.
Somerton Beach, Adelaide / uncertainThe Washington sightings combined radar returns, visual reports and official alarm. Temperature inversions offer a plausible mechanism for some returns, but the heterogeneous evidence does not support one neat solution.
Washington National Airport and the Washington, D.C. region; representative radar-site pin / uncertainWitnesses near Flatwoods reported a bright object, irritating mist and a tall, glowing-eyed form on 12 September 1952. A meteor and startled owl explain much, but not by direct proof.
Flatwoods, Braxton County, West Virginia; representative town pin / disputedJoyita’s seaworthiness problems and failed communications explain how an emergency could develop. The decision to abandon a buoyant vessel, and what happened afterward, remain unresolved.
South Pacific between Samoa and Tokelau; representative departure pin / uncertainThe Sutton and Lankford households reported a night-long confrontation near Kelly, Kentucky. Police found frightened witnesses and gunfire evidence, but no creature or trace that identified what they saw.
Kelly, Christian County, Kentucky; representative town pin / disputedThe Lakenheath–Bentwaters incident combines multiple radar reports and an interceptor account, yet gaps in timing, weather and original records prevent a secure identification or extraordinary conclusion.
RAF Lakenheath, Suffolk; representative radar-station pin / uncertainFrom 1956, the Hitchings family reported household disturbances attributed to “Donald”. Investigator Harold Chibbett kept a large record, while ordinary access and weak controls left human agency unresolved.
Battersea, London; representative district pin / disputedDyatlov Pass remains an archive of frozen conditions, injuries and competing explanations, with the strongest case still grounded in the mountain rather than the supernatural.
Ural Mountains, Russia / uncertainThe Socorro incident rests on a prompt police report and documented ground traces, yet neither the marks nor later theories securely identify what Lonnie Zamora saw.
South-west of Socorro, New Mexico; approximate incident-area pin / uncertainThe Exeter incident has named witnesses and a substantial official file, but no photograph or physical trace. “Unidentified” records insufficient resolution, not an extraordinary craft.
Kensington, near Exeter, New Hampshire; approximate field-area pin / uncertainWestall securely records a large school disturbance and sincere aerial observations. The number, path and landing claims vary across sources, while no photograph or official recovery establishes an extraordinary craft.
Westall High School and the Grange, Clayton South, Victoria / uncertainThe deaths of Manoel Pereira da Cruz and Miguel José Viana are documented; the note, masks and spiritualist interests are real clues. None establishes poison, murder or paranormal contact.
Morro do Vintém, Niterói, Rio de Janeiro state; approximate pin / uncertainMothman is interesting not because the creature is easy to prove, but because the legend gathered itself around a town, a bridge and a tragic collapse.
Point Pleasant, West Virginia / folkloreRosenheim is remembered as an instrumented poltergeist case. Surviving reports document disruptive events and investigation, while gaps in control and opportunities for manipulation prevent a secure paranormal conclusion.
Rosenheim, Bavaria; representative city-centre pin / uncertainThe Shag Harbour report generated RCMP and defence records because observers feared an aircraft crash. Searchers found no wreckage, missing aircraft or confirmed object.
Shag Harbour, Nova Scotia; approximate water pin / uncertainThe Isdal Woman case combines a documented unexplained death with coded travel records, uncertain identity and later forensic reconstruction. Espionage remains a possibility, not an established fact.
Isdalen, Bergen; approximate discovery-area pin / uncertainLoren Coleman popularised the Bridgewater Triangle as a regional paranormal zone. Its component stories vary greatly in age and evidence, and the boundary expanded through retelling.
Hockomock Swamp, southeastern Massachusetts; representative pin / folkloreThe D. B. Cooper case has a secure crime, crew testimony and recoverable evidence, but hundreds of named suspects have not produced a documented identification.
South-west Washington flight corridor; representative pin near Ariel / uncertainCattle-mutilation claims became a national mystery through alarming field appearances and uneven investigation. Forensic work explains many features without proving a single cause for every report.
Dulce, New Mexico; representative pin for a distributed United States case cluster / disputedClaims made after the Lutz family’s 1975 stay became a bestselling book and film franchise. The murders in the house were real; evidence for the subsequent haunting is not reliable.
Amityville, Long Island; representative village pin / disputedThe Tehran incident rests on a contemporaneous military message reporting civilian observations, two intercepts and aircraft anomalies. The document is strong evidence that the episode was reported, but incomplete for reconstructing the lights or failures.
Tehran and airspace south of the city; representative central pin / uncertainA shared light sighting on an Allagash lake preceded later hypnotic abduction accounts. The original observation is testimony; hypnosis does not validate the later memories.
Eagle Lake, Allagash Wilderness Waterway, Maine; representative pin / disputedThe Face on Mars became a classic anomaly because one low-resolution Viking image looked uncannily human until better imaging restored it to geology.
Cydonia region, Mars / explainedThe Wow! signal was a one-time narrow-band radio event near the hydrogen line, recorded on 15 August 1977. Its shape was noteworthy; its source remains unconfirmed.
Former Big Ear radio telescope site near Delaware, Ohio / uncertainThe Enfield case remains famous because it was recorded, argued over and repeatedly reinterpreted, which makes it a perfect archive for uncertainty.
Enfield, London / disputedFrederick Valentich’s recorded radio exchange is evidence of what he reported, not of what caused the disappearance. Disorientation, misidentification and accident remain plausible without recovered wreckage.
Bass Strait south of Cape Otway; approximate final-contact area pin / uncertainA disappearance case where winter road, confusion and delayed discovery created a mystery larger than any one clue.
Yuba County, California / uncertainVela 6911 detected an unexplained double flash on 22 September 1979. Official and scientific assessments disagreed over whether it marked a secret atmospheric nuclear test.
South Atlantic/Indian Ocean sector; approximate ocean pin / disputedRendlesham remains one of the most famous UFO cases in Britain because it produced sightings, notes and later arguments in the shadow of a military base.
Rendlesham Forest, Suffolk / disputedHessdalen’s recurring lights prompted field campaigns and automatic monitoring after a wave in the early 1980s. The label covers mixed observations, not one proven phenomenon.
Hessdalen valley; representative central-valley pin / uncertainA careful look at Britain and Ireland large-cat reports, where escaped-animal context, distance errors and local rumour overlap.
South West England / uncertainThe crew’s visual report was real and professionally documented. Radar returns were intermittent and disputed, while darkness, cloud and uncertain distance made size estimates especially fragile.
Interior Alaska between Fort Yukon and Anchorage; representative pin / uncertainThe Yonaguni formation is a genuine underwater landform. Claims of extensive human construction exceed the archaeological evidence, while limited modification of a natural outcrop remains possible.
Arakawabana, Yonaguni Island, Okinawa; approximate offshore pin / disputedThe Lake Nyos disaster was caused by a limnic eruption: deep water saturated with volcanic carbon dioxide overturned and released a dense, suffocating cloud.
Lake Nyos, Northwest Region; exact lake pin / explainedThe 22 November 1987 intrusions interrupted WGN briefly and WTTW for about ninety seconds. An attacker probably overpowered microwave programme links; the FCC inquiry found no culprit.
Chicago, Illinois; representative city pin / uncertainThe Belgian wave combined sincere observations, institutional openness and an ambiguous radar episode. It did not produce a verified craft, and its reports likely include multiple stimuli.
Eupen and eastern Belgium; representative pin / uncertainCold fusion became a lesson in calorimetry, press-first science and replication. Later reviews left room to investigate materials effects but did not validate the original nuclear-energy claim.
University of Utah, Salt Lake City; representative institutional pin / disputedThe Taos Hum became a public problem in the early 1990s when residents described a distant-engine sound. Researchers documented sincere reports but found no common external source.
Taos, New Mexico; representative town pin / uncertainChildren at Ariel School in Ruwa reported a strange object and figures on 16 September 1994. Drawings and interviews preserve their accounts, while chronology and interview method limit firm conclusions.
Ariel School area, Ruwa; representative pin / disputedThe Beast of Bodmin Moor is a cluster of reports rather than one identified animal. Escaped exotic cats are biologically possible in Britain, but the Bodmin evidence has not established a breeding population or individual specimen.
Bodmin Moor, Cornwall; representative central pin / uncertainThe Bloop was a real hydrophone recording, but not evidence of a giant animal. NOAA’s later Antarctic observations identified the same sound family in large icequakes.
South Pacific Ocean; representative acoustic-source-region pin / explainedOn 13 March 1997, reports of a moving light formation crossed Arizona before a separate row of lights appeared near Phoenix. One event has a strong military-flare explanation; the other remains disputed.
Arizona sighting corridor; representative pin at Phoenix / disputedThe anomaly was a real navigation residual, not an invented effect. Uneven radiation of onboard heat matched its magnitude and evolution, leaving no statistically significant anomalous acceleration.
JPL, Pasadena, where the anomaly was analysed; representative pin / explainedThe Black Knight is a composite legend assembled from unrelated radio experiments, Cold War tracking stories and STS-88 photographs of lost thermal insulation.
Kennedy Space Center; representative STS-88 mission anchor / explainedThe Bosnian pyramid claim lacks diagnostic construction evidence and conflicts with regional geology. Human activity occurred around Visoko, but that does not make the underlying hills artificial monuments.
Visočica hill, Visoko / explainedThe ivory-billed woodpecker controversy tests how conservation science handles suggestive video, acoustic recordings, expert sightings and the irreversible claim of extinction.
Cache River National Wildlife Refuge, Arkansas; representative search-area pin / uncertainFRBs are established astrophysical events, not unexplained transmissions in the colloquial sense. Magnetars can produce them, while the population’s diversity and emission physics remain active research questions.
CHIME radio telescope, British Columbia; representative discovery-network pin / explainedBall lightning is a label for rare luminous events reported near thunderstorms. Instrumental observations constrain some cases, while varied testimony and competing physical models leave its full scope unresolved.
Qinghai Plateau, China; approximate pin for the 2012 spectrographic observation / uncertainTabby’s Star is a genuine astronomical anomaly discovered through citizen science. Chromatic dimming supports small-particle dust rather than an opaque alien structure, while the dust’s origin remains unsettled.
Constellation Cygnus; sky location rather than terrestrial map pin / uncertainA face in a window is a useful archive case because it lets us talk about pareidolia, photography and the way expectation edits what we think we saw.
Unknown / generic domestic setting / explainedNo timeline entries match those filters.
