Built in 1908 in Wellsend, England this 2300 ton steamer called “Keystone”, (256 ft. x43 ft.) was carrying a cargo of 2230 tons of Bituminous coal from Genesee Dock at Charlotte N.Y. under the command of Capt. L Daigault. Forty five minutes past Alexandria Bay in dense fog on Oct. 12, 1912 she crossed over Outer Scow island Shoal and within minutes sank without a fatality.

One of Ontario’s premier wrecks and favorite of many divers, this steel freighter lies south of the shipping channel off Mallorytown Landing west of Brockville. The Keystorm sits in deeper water away from the shoal she hit.
