This data layer indicates the location of historic and active mine pits associated with iron mines in the Vermilion, Mesabi, and Cuyuna Iron Ranges. It was developed by the Natural Resources Research Institute by compiling data from mutliple sources. It provides the locations of all known historic and active open pit iron mines in Northeastern and North Central Minnesota. Many of the historic open pit mines have naturally filled with water and have been converted into recreation facilities.
