The discovery was made by divers participating in a unique submarine project at the acclaimed Haliburton Forest and Wild Life Reserve. Haliburton Forest is a premier Ontario attraction, well known for its commitment to education, wildlife, and the environment.
At first, divers who examined the puzzling underwater structure thought it was a geological formation, but later studied it was a manmade object. The puzzling stone structure was found at a depth of 40 feet (12 m) below the surface. It consists of a massive 1,000 lb (453 kg) elongated rock with an almost completely level surface resting on 7 baseball-sized stones, which in turn sits on a huge several thousand-pound slabs on top of a ledge.
Geologists and archaeologists were puzzled by ancient structures’ straight edges and lack of roundness. It seemed the stone could not be one of the rocks scoured by glaciers.
An underwater archaeologist who examined the structure took photos of the stone. He concluded that the existence of 3 shims was proof that the assembly of now seven rocks was the result of human activity and not a fluke of nature. Haliburton Forest turned to the services of a statistician to calculate the probability of 7 rocks falling on top of each other creating a “structure”. Albeit difficult to assess, he reported back that even 4 rocks creating a natural structure were almost unattainable, but that the probability of 7 rocks hitting at the right time and place was virtually impossible.
