Charity Shoal crater
The Charity Shoal crater is a 1.2–1.4 kilometers (0.75–0.87 mi) in diameter circular feature that lies submerged beneath the northeast end of Lake Ontario about 12 kilometers (7.5 mi) southwest of Wolfe Island, and 25 kilometers (16 mi) south of Kingston, Ontario, at about latitude 44° 02′ N and longitude 76° 29′ W. It is hypothesized to be a Middle Ordovician impact crater from about 460 million years ago. == History == On December 5, 1897, the steamship Rosedale grounded upon the rocks of East Charity Shoal in the eastern end of Lake Ontario during a northwest gale.
