Exploring the Underwater Pyramids and Structures of Rock Lake

Mary Sutherland and her team are mapping the bottom of Rock Lake in search of underwater pyramids, Rocky the lake monster, and other mysterious anomalies reported by locals.

Are there pyramids at the bottom of Rock Lake, or is it a hoax concocted by the town of Lake Mills to attract more visitors during the Great Depression? Author Mary Sutherland believes rumors of ancient structures beneath Rock Lake are true, and may be connected to Atlantis and the Biblical stories of Solomon’s Temple.

The video below documents a day Sutherland spends with Frank Joseph, author of The Lost Pyramids of Rock Lake, and crew exploring an area where they believe to have found a black stone pyramid during a previous trip.

According to Sutherland’s website, the ancient culture that lived in the area purposefully built these structures to harness electromagnetic energy from a ley line that stretches up from the Mayan citadel of Tikal through Lake Mills, and even into Mayville where crop circles appeared in July of 2003.

“Strange things happen around the area of Rock Lake,” she writes on her website. “People see things that aren’t there – Ice fishermen can’t start their chainsaws out on the ice, but back on shore they start fine – They return to the ice and again run into the same problem. Scuba divers, trying to film the underwater pyramids can’t get their cameras to work. Other divers, preparing to dive into the waters of the pyramid, are overcome with a sense of dread. It is apparent that there is an energy disturbance going on in the area – strong enough to cause mechanical failure as well as affecting the human consciousness.”

That might explain why Lake Mills seems to be a hot bed of strange activity, including the hissing Rock Lake Terror first reported in 1867, UFOs witnessed going into and out of the lake, and other mysterious phenomena.

  1. Hi Anthony, I love your comment is well said. 100% truth.

  2. I am curious to know if you have found anything? I do believe that as humans we are very in touch with tomorrow and not concerned with yesterday’s which leaves us pissing on today. I am not trying to be rude I am a ancient history junkie and would honestly like to see what is hidden deep beneath the ancient waters that surround our lives. I love space the stars and all it may hold yet the ocean and lakes must first be unlocked and understood before we try to figure out the progression of the stars.

  3. Out on the lake about a month ago launched on the north end of the lake and joy rides around the east and south sides when I got to the west end my tranny was slipping in and out all the way back to the launch site I took my boat out the following week and everything was normal again
