Beaver Harbor Light - Beaver Island, Michigan. This light tower is the second to stand on Whiskey Point, the site of the original Lifesaving Station on Lake Michigan. The first tower was built in 1856, but lasted less than twenty years due to poor construction. After this one was built, a Light Keeper's house was added, which lasted into the 1940s. The Light itself has been automated for some time.
