History Mystery* In 1985, a dive tour operator discovered underwater structures that resembled pyramids off of the coast of Yonaguni-jima, Japan. The underwater pyramids have marks on them that indicate they may be manmade. Tools used to hew the structures have been located in the area. American geologists deny that the pyramids were made by an ancient civilization. They believe, though there is contradictory evidence, that the structures are natural formations.
