Silurian Dolomite of the Niagara Escarpment. In some places, the bluffs along the bay are 200 feet high. Silurian Dolomite is hard, and fractures horizontally and vertically. This makes it a good rock for building structures, like the School House. They also readily crack off the cliff sides along the bay, and formed a sandless beach. Piles and piles of roughly square rocks are a enormous temptation to the builder inside most people. There were man-made stacks of rocks as far as the eye could see.
The general term for a man-made pile of stones is 'cairn'. Cairns were used to mark trails, landmarks, serve as a monument, or act as a protective entity. The 2010 winter Olympics in Canada introduced the world to 'inuksuk'. An Inuit word meaning "something which acts for or performs the function of a person". Often rock stacks are made to resemble to human form. So often, in fact, that there are words for these rock forms in several languages:
- inunnguaq - Inuit meaning "imitation of a person"
- steinmann - German meaning "stone man"
- steenman - Dutch meaning "stone man"
- ometto - Italian meaning "small man"
The question remains, Do they protect the shore from the ships, or the ships from the shore?
