The Bloop

added30 August 2026

In 1997 hydrophones belonging to the US National Oceanic and Atmospheric Administration recorded an ultra-low-frequency sound in the South Pacific loud enough to be picked up by sensors three thousand miles apart. Its profile resembled a biological one, and for two decades the Bloop was the leading exhibit for anyone who believes in undiscovered giants in the ocean. NOAA settled it in 2012: an icequake, an iceberg fracturing off Antarctica. The sound stopped being a mystery but remains one of the best-known audio files in internet history.

Nahuel Huapi and Nahuelito

A deep glacial lake in Argentine Patagonia where a creature was described long before Loch Ness: the Mapuche were telling the Spanish about it in the eighteenth century. In 1922 the Buenos Aires zoo announced an expedition to find a plesiosaur and the story went round the world. Nahuelito is described as a humped back some fifteen metres long; there are many photographs and not one convincing.

UFO sightingGreen

Victoria and the Corridor over the Paraná

Since the 1990s this Argentine town on the bank of the Paraná has collected so many reports of lights over the delta islands that locals call the stretch a corridor. Most sightings are made from the Rosario–Victoria bridge and the roads along the shore. The town treats it practically: there is a municipal UFO route and signposts on the way in. Sceptics point out that airways cross the delta and that temperature inversions over the wet islands are common, producing the shimmer and apparent movement of stars near the horizon. That accounts for part of the reports; the flow of them has not slowed over the years.

Capilla del Monte, the Town That Lives on It

A town at the foot of Cerro Uritorco in the Argentine province of Córdoba, known across Latin America as the capital of UFO tourism. In January 1986 a scorched oval about a hundred and twenty metres long was found on the slope, and its origin was never established; the town's fame begins there. Since then it has held the annual Alta Uritorco festival, its hotels cater to energy tourism, and on New Year's Eve thousands climb the mountain to wait for lights. Local esoteric tradition places an underground city, Erks, inside the mountain. No expedition has found anything of the kind, and it has made no difference at all to the visitor numbers.

Bermuda Triangle

The Bermuda Triangle (also known as the "Devil's Triangle") is a loosely defined oceanic region in the western North Atlantic, conventionally demarcated by points connecting the Bermuda archipelago, Miami (Florida), and San Juan (Puerto Rico). Encompassing an area of roughly 1 to 1.5 million square kilometers, the sector encompasses the Florida Straits, the Bahamas, and portions of the Sargasso Sea. Throughout the latter half of the 20th century, the zone became the premier global archetype of maritime and aviation lore, reputed across popular culture for the unexplainable disappearance of dozens of vessels and aircraft.

Kashkulak Cave

Kashkulak Cave (colloquially known as the "Cave of the Black Devil" or the "White Shaman's Cave") is a karst cavern system in the Batenevsky Ridge of the Kuznetsk Alatau mountains, situated in the Shirinsky District of Khakassia, Russia. Featuring a three-tier network of galleries descending to a depth of 49 meters with over 800 meters of mapped corridors, the site earned notoriety in the late Soviet period as an anomalous subterranean hotspot where explorers and scientists experienced acute panic attacks, disorientation, and waking hallucinations.

The Molebka Triangle

The Molebka Triangle (also known as the M-Zone or the Perm Anomalous Zone) is a geographic area spanning roughly 70 square kilometers in the Kishertsky District of Perm Krai, Russia, situated along the Sylva River near the historic village of Molebka. In the late 1980s, this remote pocket of Ural taiga transformed into the Soviet Union's first and most famous recognized "paranormal zone," becoming a global epicenter for UFO tourism and ufological expeditions.
