Mary Island is located roughly 25 miles (40 km) south of Ketchikan and about the same distance north of the Canadian border. The Mary Island Light Station, Alaska’s fourth lighthouse, was built here in 1902.
On the night of September 13, 1906, the steamship Oregon, captained by H.E. Soule, was en route from Seattle, Washington to Valdez, Alaska with fifty passengers and about 900 tons of freight aboard. Due to heavy fog, the vessel was three miles off course when it ran hard aground on rocks fifty yards offshore from Hinchinbrook Island.
