Rock Lake (Tyranena) is a feature in southern Wisconsin that is probably best known for its many underwater structures, some of which are pyramidal in shape. Some suggest that they were built by the indigenous Aztalan people. Frank Joseph has written two books about the lake, Atlantis in Wisconsin and The Lost Pyramids of Rock Lake . He maintains that the anomalies are burial mounds of people who worked the huge copper mines of Michigan from 3000 BC until around 1200 BC. He further claims that “the mines were excavated and operated by engineers from Atlantis.”[104.239] Native American traditions describe these people as pale-skinned, with hair like fire!
Even more exotic are claims that the lake can produce “energy disturbances” that has caused equipment to malfunction(a) as well as high energy frequencies that effects human consciousness!(b). For good measure a serpent monster has also been claimed for the lake(c).
The Rock Lake Research Society was founded in 1998 and included experts with the objective of documenting and preserving the archaeology of the lake. Their work has continued ever since. One of the founding members, the late Archie Eschborn, has written The Dragon in the Lake , which encapsulates the research and theories regarding Rock Lake.
