Extent of available data.
This data layer identifies the underground mine properties within portions of the Mesabi Range. It was developed by the Minnesota Department of Natural Resources and is comprised of the documented footprints of natural iron ore underground mine properties on the Mesabi Range east of the Itasca/St. Louis county line. These are the owned/leased lands associated with a given mine on which permitted mining-related activities (mining, processing, stockpiling, etc.) occurred. This information can be used for mapping, documentation, stockpile recovery, monitoring, analysis, and land use planning purposes.
