Thunder Bay Island Light located on Thunder Bay Island’s southeast tip is one of the oldest operating lighthouses in Michigan. The third operating U.S. lighthouse in Lake Huron was built here in 1831 but it disintegrated almost at once and was rebuilt in 1832 of local limestone. This 40-foot (12 m) 1830s light tower was raised 10 feet (3.0 m)) to a height of 50 feet (15 m) in 1857 and sheathed with brick. A fourth order Fresnel lens was installed.
