Is an old working under a property here?

The mine records hold 17 named mine sites inside the county, 14 of them worked out or abandoned; the old survey maps add 89 holes drawn inside the county, 1 of them shafts or tunnels. The minerals the records name are Garnet; Iron; Aluminum.

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. New York has no coal AML program; the DEC database covers permitted mines, not historic underground workings.

Hamilton 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. 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.

Check with the mine map office named here before you rely on it, and have a qualified engineer look at any ground you are worried about.
