In 1986 a diver in the waters off Japan's southern Yonaguni, Jima Island
discovered series of mysterious underwater stone structures
Possibly the ruins of MU a rumored ancient lost civilization
believed to have sunk into the sea after a large earthquake and tsunami event
According to Masaaki Kimura a marine geologist of Japan's University of Rio qu who has studied the formations for 15 years
The ruins consist of ten separate structures connected by roads and surrounded by what appear to be a retaining walls
including five temples and a castle
Kimura states the structures are about five thousand years old and though he was initially skeptical that this was an ancient human city
He now believes it is quote difficult to explain away their origin as purely natural
given overwhelming evidence of man's influence on the structure
Kimura has found clues that the slabs were mined from a quarry and even found characters and faces carved into the stones
including one example of what appears to be a sphinx of Chinese origin
Indicating the alleged builders were influenced by Asian culture if not Asian themselves
The Japanese government, however has yet to recognize the underwater metropolis as a site of cultural or historic significance pending further investigation
Hired in 2007 to survey old shipwrecks at the bottom of Lake, Michigan
underwater archaeologists mark Hawley and Brian Abbot used a sector scan sonar device
Producing these circular topographical photographs on the lake bed and accidentally revealing that mysterious Stonehenge like construction beneath the surface
about 40 feet below the surface many large stones are peculiarly arranged in an unusual circular pattern and
One Boulder seen here appears to some to have a carving of a mastodon, which has been extinct for roughly 10,000 years
If verified this would suggest the feature was created by humans before the creature 16
And before the site was submerged after the last ice age
According to researchers the best evidence that the stones were placed by humans and are not a natural formation is that they are all
uniformly the same size
Humans are believed to have inhabited the Great Lakes region for nearly twenty five thousand years
And there are many other prehistoric petroglyphs in the region
But historians are baffled as to how an ancient hunter-gatherer civilization could have constructed a structure as elaborate as the Lake, Michigan Stonehenge
In the summer of 2003 a sonar survey revealed a mysterious circular object underwater in the Sea of Galilee
That a scuba dive team confirmed was a massive cone-shaped structure made up of quote untuned basalt cobbles and boulders
stacked together
with an impressive base roughly 230 feet across and rising 32 feet tall
Researchers say the stone structure is almost certainly human-made. They believe it could be up to 4,000 years old
Postulating minute may be a cairn the pile of rocks used by various civilizations throughout history to mark burial sites
Whatever its purpose such an enterprise is quote
indicative of a complex will organized society with planning skills and economic ability according to archaeologists
It may even be associated with the lost city of Betty era
Which lies just south of the underwater ruins and was the region's richest city circa 3000, BC
Most likely the formation was once constructed on land only to have been submerged over time as sea levels have risen in the area
The next step for researchers is an underwater
Archeological excavation to unlock the mysteries of the unique structure and the civilization that built it
On a Caribbean vacation in 1968 three divers discovered a mysterious
underwater formation just off the coast of the Bahamas, North Bimini Island
The divers reported encountering the quote pavement of what appeared to be a half mile long road made of limestone
along with quote two linear features lying shoreward of it composed of flat lying tabular and rectangular blocks
It has been named Bimini Road and has drawn curious geologists archaeologists and anthropologists from around the globe to investigate
the rectangular stones are heavily rounded on top due to erosion from the sea giving them the appearance of loaves of bread and
unfortunately eliminating any evidence of grooves or tool markings on the stone surfaces that would indicate a human origin
Many geologists believe Bimini Road is a naturally occurring phenomenon a beach rock that's broken up into rectangular and political blocks over time
similar phenomena had been observed in other parts of the world
But because so little is known about the structure a fierce debate over. Whether the road is man-made
continues
In 2008
divers participating in a submarine project for the Halliburton forests and wildlife preserve at Ontario Canada's McDonald Lake
Discovered a mysterious ancient stone structure that consists of a giant thousand pound elongated rock with a nearly level surface
It rests on seven other individual baseball sized stones, which themselves set atop a slab of stone in the lakes floor
originally believed to be a natural geological formation further investigation revealed it is more likely human in origin a
Similar natural formation called a perched erratic occurs when a boulder is deposited on top of another rock as glaciers move and melt
But researchers determined the likelihood of a boulder naturally resting atop seven stones is statistically impossible
Also suggesting human construction are the stone straight edges although evidence of carving or markings from tools has likely eroded over
The structure could have been built between 9,000 and 7,000 BC
But archaeologists have no understanding of how the heavy rocks were stacked or what function the enigmatic structure served to its prehistoric builders
