One of the easily identifiable "Art-Deco" style lighthouses of the late 1930s. From what I have read, this tower never housed a lantern room like many of the Art-Deco style lights did. This light took the place of the Charity Island Lighthouse.
Here is a much better close up picture of the Gravelly Shoal Lighthouse courtesy of the USCG Website.
Directions: The lighthouse sits off shore in Saginaw Bay. The best way to see the light is via boat. There is a ferry service that passes by it on the way to the island. Since I didn't have time to travel to the island, I got a distant shot from shore. From US-23 in Au Gres, I took US-23 north 4.8 miles to Point Lookout Road. I then followed Point Lookout Road to the end, and made a left onto Michigan Ave. I followed this to the end where there was a break in the houses and could see out into Lake Huron / Saginaw Bay. From here, you can look out and see the light with a telephoto lens.View more Gravelly Shoal Lighthouse pictures
