At first it was thought to be a glacial erratic, but archaeologists now say that this pedestaled boulder in Ontario's MacDonald Lake could have been placed in reference to landscape or even a relic population of lake trout.
Haliburton Forest is a premiere Ontario attraction, well known for its commitment to education, wildlife and the environment. Repeatedly staff of Haliburton Forest would stumble upon an unusual stone structure, perched on top of a rock ledge at a depth of 40 feet below the present lake level. Initially the structure was considered a complex version of a 'perched erratic', those monstrous rocks, ferried by the glaciers thousands of years ago and dumped where they happened to melt at the end of one of the recent cold-freezes.
From across northern North America, examples of compound perched erratics are known, where 2 or even 3 rocks happened to land on top of each other, leaving behind a natural structure. Initially, this is what was considered to be the origin of the Haliburton Forest mystery rock formation. When several geologists and archaeologists saw images of this object - a 1,000 pound, elongated and south pointing rock sitting on baseball-sized stones at each end, which in turn, were resting on a massive, several thousand pound slab on top of the ledge, they expressed doubts about its natural origin. But could the structure be of human origin? If so, how could that be established?
Haliburton Forest engaged the services of an underwater archaeologist to examine the structure. Before diving, he explained that so far he had never encountered man-made rock-cairns, which were stabilised without the help of shim-stones. If he found these, it would convince him of the structure's man-made, not natural, origin.
After a 30 minute dive examining the rock assembly closely and carefully, taking pictures along the way, the expert emerged with his unequivocal conclusion: the existence of 3 shims was proof to him that the assembly of now seven rocks was the result of human activity and not a fluke of nature.
Subsequently, 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 was almost unattainable, but that the probability of 7 rocks hitting at the right time and place was virtually impossible.
