10 Strangest Underwater Discoveries

10 Strangest Underwater Discoveries 10 Lake Michigan Stonehenge Our submarinal journey begins at Lake Michigan, where in 2007 archaeologists were scanning for shipwrecks

Instead, 40 feet below the surface they found a line of large stones, leading to a circular formation in the centre This placement appeared too intentional to be naturally occurring But the most interesting aspect was what appeared to be carvings on one of the stones It seemed to show a Mastodon, the extinct ancestor of the elephant that died out over 10,000 years ago This lead Dr

John O’Shea from the University of Michigan to suggest it might be an ancient hunting structure known as a ‘drive line’, which guides prey towards a waiting ambush This time frame is corroborated by the fact that the lake bed was last dry before the end of the last Ice Age, around 12,000 years ago If man-made, the structure must have been made around then, before being submerged when glaciers melted This conflicts with current beliefs that humans were incapable of erecting monumental structures at this time in history 9

The Russian Wreck Onto Egypt now, 24 metres below sea level at Zabargad Island That’s the location of a ship known only as ‘The Russian Wreck’ Discovered in 1988, the wreck resembles a Russian Fishing Trawler, but carried an inordinate amount of electronic equipment for such a vessel Said equipment instead seemed to point to surveillance or communications This has lead to a commonly accepted theory that the boat was in fact a spy ship from the Cold War

This explains the lack of identifying features on the ship, as well as it’s peculiar locale In the 50s, during the Cold War, the Soviets regularly opted for commercial vessels like fishing trawlers when gathering covert intelligence, and there was believed to be a soviet surveillance facility nearby in the Yemen However, this has all yet to be confirmed by any Russian officials and may remain another unsolved aquatic mystery 8 Cuban Underwater City Typically, man made structures aren’t found any more than 400 feet below sea level

Evidence suggests that sea levels have not fallen below these levels in the time that humans have walked the earth It’s this that makes Cuba’s ‘underwater city’ a striking anomaly During a Cuban-Canadian expedition in 2001, sonar images depicted what appeared to be an ancient urban complex, covering 2 square kilometers and submerged over 2,300 feet underwater Geologist Manuel Iturralde suggested it would take 50,000 years for such a structure to sink to this depth, but that no known cultures at that time were capable of building it Other suggestions are that a city may have been submerged by tectonic activities

But Grenville Draper of Florida International University claimed that no tectonic activity of that magnitude has ever been recorded At such a depth, further study has been limited, but should it be confirmed as man-made, it could change history as we know it 7 Bimini Road Just off the coast of North Bimini island in the Bahamas, you can find the Bimini Road Discovered in 1968, the road is a 0

8 kilometer long collection of near rectangular stone slabs arranged like a long cobbled path It’s also 18 feet under the sea Its puzzle-like arrangement and 90 degree angles have many convinced the road is man-made, but several geologists have remained skeptical They suggest that the formation may be explained by large bedrock breaking up into tessellating rectangles, which the current has worn down over time to appear as separate rocks This was supported by a National Geographic commissioned study which suggested there weren’t enough similar blocks lying in the vicinity to provide evidence that more road existed either side of the stretch

However, if the road is naturally occuring, it’s just as intriguing a find, as no similar formation has been discovered to date of this scale or precision 6 The Phantom of Subic Bay While there’s no shortage of military aircraft on the ocean floor, one in particular has drawn significant interest At the bottom of the Luzon Sea, Philippines, lies the carcass of a Phantom F-4 fighter jet This model was primarily used by the US army during the vietnam war, which explains its location

So far, so ordinary However, the ship couldn’t have crashed, given both the lack of damage and the fact it was completely stripped for parts So what happened? Well, sometimes during this period, damaged aircrafts would be stripped like this, and very rarely pushed overboard for space Others suggest it may have been aboard the aircraft carrier USS Forrestal In 1967, the carrier suffered a series of internal explosions in the nearby Gulf of Tonki, causing 134 to lose their lives

Some suggest that as the damaged Forrestal made for a naval base in the Philippines, the Phantom was cast off to conserve weight Sadly, rust has damaged the craft beyond identification, and its origin may never be revealed 5 Yonaguni Monument In 1986, a diver from the island of Yonaguni discovered a strange structure of rock, 16 feet below sea level The formation covers around 64,000 square feet and is 90 feet tall at its highest

In the stone are sharp angles that appear to form steps, roads and terraces, leading to an long debate over the structure’s origin Professor Masaaki Kimura, a marine geologist from the University of the Ryukyus, leads the argument that the monolith is man made What he believes to be tools found at the site could point to a 5,000 year old civilisation, submerged by a large seismic event Dr Robert Schoch of Boston University disputes these claims

He posits that the formation is natural, with currents shaping the rocks over time and shifting tectonic plates causing the more pronounced, angular shapes Japan’s placement on four tectonic plates could support either theory, but their government’s hesitance to fund further investigation keeps the monument shrouded in mystery 4 Ancient Computer We’ve all been tempted to hurl our computers into the sea, especially after reading YouTube comments, but what some call the “First Computer” is even lying in the deep The Antikythera mechanism takes its name from the Greek island by which it was discovered

150 feet below the Aegean Sea, divers found the analog device in 1900, on a Roman ship, believed to have shipwrecked in the 1st Century BCE The clock-like device had at least 30 gears, and inscriptions on its numerous parts offer instructions as to its use These suggest it was made to calculate dates and predict astronomical phenomena Similar mechanisms of this complexity don’t re-appear in history books until close to 1500 years later in Europe Some have theorized that its inventor was the ancient astronomer Hipparchus, the inventor of trigonometry

As one of the first to theorize that the Earth revolved the sun, it’s believed the device may have been created to help prove this 3 Pavlopetri Pavlopetri sounds like a great place to live – two storey houses, temples and a complex water management system that surpasses the design of some modern cities even today However, as it’s 13 feet underwater, the commute is a bit of a nightmare Pavlopetri was discovered in 1968 by a team of English archaeologists, in the Peloponnese region of Laconia, Greece

Although no one knows the original name of the city, or its role in ancient world, the ruins have been dated to around 2800 BC It’s believed that the city was submerged 1000 years BC as the result of an earthquake The site is protected by UNESCO as an area of cultural heritage, due to its significant historical and cultural implications Possibly the most significant of these is its regular attribution by scholars as Plato’s inspiration for the Lost City of Atlantis 2

Locomotive Graveyard In 1985, sailor Paul Hepler was mapping the bottom of the ocean near New Jersey As you do 27 meters under the water, he made the rather strange discovery of two locomotive trains, sat upright on the ocean floor The trains were rare Planet Class 2-2-2 T’s, a smaller model which was quickly discontinued before many were manufactured Their rarity was no help in identifying the vehicles though

No records exist of two such trains being lost in the area or, even weirder, of these two engines having been built to begin with Experts believe the locomotives were being transported from Boston to the Mid-Atlantic when a storm hit the barge carrying them At this point, the engines either fell from the ship or were pushed intentionally to avoid it capsizing With the records either lost or destroyed however, it remains a mystery 1

The Underwater City in the Gulf of Khambhat When Indian oceanographers were scanning the Gulf of Khambhat in 2001, they discovered a collection of geometrical structures by accident Using a technique known as sub-bottom profiling, researchers found the structures had deep foundations, spurring claims that they may have been the remains of an urban settlement This was supported by artefacts found at the site, including construction material, pottery, and human bones When carbon dated, these items were found to be nearly 9,500 years old Other cities on this scale are not on archaeological record until 4,500 years ago, so this would radically change understanding of the development of urban civilization on the planet

However, some doubt has arisen over the validity of these findings, with some pointing to the heavy current in the area This could explain the presence of these artefacts at this location, perhaps having originated elsewhere and been moved to the site So that was 10 Strangest Underwater Discoveries With only 5% of the ocean explored, what else do you think we'll find down there?
