Point Iroquois Light occupies a strategic bluff in Michigan where Whitefish Bay meets the western end of the St. Marys River, a long-used landmark on the route between Lake Superior and the other Great Lakes. The point also preserves a deeper past in its Native name and its association with a 1662 Ojibwe killing of Iroquois warriors. As traffic through the Soo Locks grew, a lighthouse opened there in 1856, but structural concerns led to its replacement in 1870 by the present white brick tower. For 93 years it guided shipping, later adapting with new fog signals and expanded quarters before its deactivation in 1962.
