Is an old working under a property here?

The mine records hold 125 named mine sites inside the county, 81 of them worked out or abandoned; the old survey maps add 56 holes drawn inside the county, 4 of them shafts or tunnels. The minerals the records name are crushed stone; Mercury; Stone.

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.

Marin County: the boundary from the Census Bureau, and one dot for each old mine or hole on record inside it. Purple is a shaft or a tunnel. Hover a dot for its name.

Rows taken off the old survey maps open the USGS record of what sits at that spot, because no single feature on those maps has a page of its own. Rows from the mine records open their own USGS page.

California abandoned mine maps ranks every county and town in the state by the workings recorded inside it, names the office that holds the mine maps, and says what to do if the ground moves.
