Au Sable Light Station

Located within Pictured Rocks National Lakeshore, this light stands on Au Sable Point on the south shore of Lake Superior, approximately 12 miles west of Grand Marais, Michigan.  Built in 1873-1874, the light tower's base diameter is 16 feet with a height of 87 feet. The lens focal plane is 107 feet above lake level. A fog signal building was built in 1897.  The original two-story keepers dwelling was attached to the light tower in the back. In 1909, the building was added on to the front so it would accommodate two families. One lived upstairs, one down. The head keeper's residence was built in 1909.
