The park is located north of the city of Calumet, in Itasca County, Minnesota. The park provides access to fossil material exposed by mining from the Cretaceous era Coleraine Formation. In 1892, the land was leased for mineral exploration. It was leased again in 1900 and mining began in 1913. In the years it was in operation, the mine produced 63 million tons of iron ore. It grew to become the sixth largest producer in Minnesota.[3] Historic buildings include the office building (c. 1930), laboratory (c. 1930), maintenance shop (c. 1930), truck repair shop (c. 1919), wooden water tower (c. 1919), and community club (c. 1915).[4] After the mine closed, the Iron Range Resources and Rehabilitation Board acquired if for a dollar. They converted the community club building into a museum and visitors center and gave tours. The former mine was listed on the National Register of Historic Places in 1986 as a historic district, and the Minnesota Legislature made Hill Annex Mine a state park two years later. Flora and faunaConservationists have added vegetation to rehabilitate areas damaged by open-pit mining. The landscape is home to grouse, deer, coyotes, timber wolves, and black bears. Raptors, including eagles, peregrine falcons, and hawks have returned to the park.
