The Miners Memorial Heritage Park (MMHP) encompasses the former iron ore mining locations within the City of Ironwood (locally known as the caves area). The discovery of these mines resulted in the establishment of the City of Ironwood in the latter part of the 19th century. The last iron ore mine in the City of Ironwood closed in 1966. Take the trails for hiking, cross country skiing, snowshoeing, and more! Each summer, attend the Art in Miner’s Park exhibit to see pieces by local artists.
