Exploration History

1870-1880 : a small quarry was opened here, immediately adjacent to a small bay on the W side of the island. Granite from here was used in Toronto as cobblestone for the Sherbourne streetcar track. It is probable that quarrying here was contemporaneous with that on nearby Quarry Island, as the amount of material shipped to Toronto exceeds the dimensions of the quarry here. The same family was also involved in both sites.
