Out on the reef, about a mile from from the coast, stands the Port Austin Reef Light on its own octagonal concrete island. It marks the turning point at the junction between Lake Huron and the Saginaw Bay. The sides of the base are 34 feet each. There are two structures on the base, namely the six-story light tower and the shorter, larger fog signal building. The light is 76 feet above the mean low tide. The light was automated in 1953 and decommissioned in 1979. It was rescued from dismantling and has been placed in the Registry of Historical Places.
