This data layer indicates the locations of historic and active tailings storage facilities associated with iron mines in the Mesabi and Cuyuna Iron Ranges. It was developed by the Natural Resources Research Institute by compiling data from multiple sources. Opportunities exist for repurposing much of the tailings materials as sources of aggregate and continued recovery of iron units.
