YONAGUNI MONUMENT

The following pictures are from the Temple of Mu website that are there on sequential pages, reproduced here on one page together with the corresponding texts (remarks by author in brackets).
 

This tablet, known as the Okinawa Rosetta Stone, tells a story in ancient symbols. It describes a peaceful ruler and his castle on land, which after the occurrence of a catastrophic event, ended up under the waves.

This is a water channel used to move water from one location to another. It might be ceremonial, or could have been used for drainage. This is typical Okinawan construction and can be seen in other architectural work throughout the area [electronically stylized]
 
The stones with the split
 
These large, deep holes most likely served as construciton hoists. The wooden columns set in here would have been used like cranes to raise and lower giant blocks of stone.
 
This is one of two stylistically carved turtles atop the monument. [probably electronically stylized]
 
A huge boulder mysteriously perched upon its own platform appears ceremonially placed.
 
The diver is peering into the eye of this colossal head that looks eerily similar to the giant statues on Easter Island.
 
Note the scale of the divers in front of one of the giant turtles at the top of the monument. You are looking at its triangular head with its front legs out-stretched.
 
Stalactites and stalagmites can only be made on land. The many caves around Okinawa with their submerged stalactities indicates that much of the area was above water at one time.
