Whitefish Point Lighthouse, the oldest active light on Lake Superior, began operating in 1849, though the present tower was constructed later. Early a stopping place for Indians, voyageurs, and Jesuit missionaries, the point marks a course change for ore boats and other ships navigating this treacherous coastline to and from Saint Mary's Canal. Since 1971 the light, fog signal, and radio beacon have been automated and controlled from Sault Sainte Marie.
