A tall but fragile edge of the escarpment on the other side of the quarry is ready to crumble
The nature is heeling injuries inflicted by humans and maybe in the next 100 years the old quarry will stop being visible at all.
As I was walking through this quarry I was wondering what it was like to work there, what kind of stones were extracted, where were they delivered?
The only clue regarding the origins of this quarry that I was able to find was that one meager sentence from the Bruce Trail website.* If you know/were able to find more information, I would be happy to know that.
