Abandoned mine records
Old mine workings in Crystal Lake
Where the workings are, and the office that holds the mine maps.
The mine records hold 1 mine site inside the city or town limits: 1 site producing when the record was made; the old survey maps add 10 holes drawn inside the city or town limits, 0 of them shafts or tunnels.
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. The Illinois Mine Subsidence Insurance Fund is a not for profit created by statute, not a state agency; the cover is bought through the homeowner insurer.
Crystal Lake: 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 pale shapes with a name around it are the neighbouring places, from the Census Bureau. Hover a dot for its name.Illinois mine map and abandoned mine records
