Although Poe Reef Lighthouse is located about 20 miles from Old Mackinac Point Lighthouse, it is much more remote. It lies completely in Lake Huron about two miles off shore. It was built in 1929 and frequently had waves hit its base sending water up as high as the 4th floor. It was decommissioned in 1974 and is up for auction — opening bid $10,000. The first photo shows the Lighthouse nearing completion.
