This stone shows signs of ancient human manufacture. Percussive bulbs result from being hammered and chipped, and facial flaking along the sides are strong indicators. It was retrieved in April 2010 from the then drained shoreline of Silver Lake millpond in Port Dover, Ontario. In the vicinity of the stone were animal bones and glacial till.
According to Ontario’s Heritage Act– municipalities must
- Provide clear standards and guidelines for the preservation of provincial heritage properties.
- Enhance protection of heritage conservation districts, marine heritage sites and archaeological resources.
Even when cultural artifacts are not immediately discovered, a cultural assessment must take place to establish any archaeological remains. The Cayuga Bridge construction project was delayed due to this requirement.
