Black River Island is an island in Lake Huron. It is part of a series of shoals around the mouth of Black River and is 3⁄4 mile (1.21 km) NE of it.[1] The island is included within the unincorporated community of Black River in Alcona Township.
The uninhabited rocky island is about 1,000 feet (305 m) long.[1] Its area is less than one acre[2] and varies with lake levels.[3]
The shoals in the area are a boating hazard.[4][5] The schooner William H. Rounds, carrying a load of coal, ran aground on the island in May 1905 and was destroyed.[6][7] Further south the tugboat Loretta, carrying a load of chain, broke its propeller and caught fire in October 1896.[8] The Ishpeming, a schooner carrying a load of coal, ran aground in November 1903. It was scrapped and abandoned.[9] These are marked by buoys.
In the past, owners of the island have shown interest in selling it to wildlife organizations.[3] The island is approximately 7 miles south of Scarecrow Island which is part of the Michigan Islands National Wildlife Refuge.
