In the late 1800s when iron ore mining was in its prime, a group of 27 miners were killed when the Mansfield Mine caved in and its shafts flooded with water from the Michigamme River. People who live close by can sometimes hear screaming and noises like someone was hitting a pick against a rock. Apparitions can be seen in and around the water where the mine filled with water. Lights of the mining helmets are seen coming from below the water.
