A point in either file is a location, not a property line: the sheet shows the opening on the surface, not the rooms under it. The record that shows what runs under a parcel is the mine map. The OSMRE National Mine Map Repository holds scanned underground mine maps and answers requests for a named mine or an area. GeoWebFace shows historic mining sites as points; no agency page with underground workings outlines was found, and the OSMRE National Mine Map Repository holds Michigan maps.

Ontonagon County: the boundary from the Census Bureau, and one dot for each old mine or hole on record inside it. The purple dots come off the old survey maps and the darkest of those are shafts and tunnels; the red, green and orange ones are mine records. The small open circles with a name are the towns and the pale shapes around the edge are the neighbouring counties, both from the Census Bureau. Hover a dot for its name.
