6x6 Waugoshance Lighthouse

Built in 1851 to replace a wooden lightship that had served since 1832, to mark a dangerous shallow area of northern Lake Michigan in the approach to the Straits of Mackinac.

The station sits on a wooden crib that was sunk and filled with stone. The crib structure was the first major crib built for a lighthouse on the Great Lakes. The crib was rebuilt with massive limestone blocks in 1867-70. A conical brick tower sits above the burned out shell of a round 2-story dwelling. The tower was encased in iron plates to protect the deteriorating bricks, but the iron work has fallen into Lake Michigan over the years.
