Two historical lighthouses have served as the Michigan Island light. The older was constructed in 1857, but not activated until 1869. It served until 1929, when it was replaced by a taller, 118-foot (36 m) skeletal tower, which is still operational.
The 3½-order Fresnel lens, coupled with a 24,000-candela electric light and the 170-foot (52 m) focal plane (aided by its placement on a cliff) aided by the tower's location atop the cliff, made the light range of visibility to a "remarkable 22 miles."[3] This was a relative rarity, being one of only a dozen used around the country, most of which were on the Great Lakes,[4] These lights were typically reserved for places that were an especially serious hazard to navigation. See, for example,Sturgeon Point Light. Other Great Lakes lights that had 3½-order Fresnel lenses were at (in alphabetical order): DeTour Reef, Eagle Bluff, Grays Reef, Huron Island, St. Helena Island, and Toledo Harbor.[4]
The structure shares its design with towers at Rawley Point Light on Lake Michigan and Whitefish Point Light at Lake Superior's eastern end. However, the Michigan Island tower has a small brick building located at the base of the center tube, apparently a workroom for the early lighthouse keepers.[7]
Most of the Apostle Islands light stations can be reached on the Apostle Islands Cruise Service[8] water taxi or by private boat during the summer. During the Annual Apostle Island Lighthouse Celebration,[9] a ferry tour service is available for all the lighthouses. During the tourist season, volunteer park rangers are on many of the islands to greet visitors.[10]
