Local record guide
What we hold on Thornton, and who keeps its records.
Local profile
Thornton is an incorporated place in Cook County, a place of 2,386 people, and keeps its own council and town business records. Chicago, the county seat, is where the county offices are. Our Cook County page lists each county office.
Abandoned mine records
Where the workings are, and the office that holds the mine maps.
From the two federal mine files
The USGS mineral file records 4 named mine sites inside the city or town limits, 2 of them worked out or abandoned; the USGS topographic mine features add 8 features mapped inside the city or town limits, 0 of them shafts, adits or tunnels, digitised from the old survey sheets. The minerals the records name are Limestone, General; crushed 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. 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.
Please read: Everything here can be wrong. This is information, not a guarantee: the two federal files can be wrong, incomplete or out of date, the boundaries and the geocoder can be wrong, a point is a location and not a property line, and nothing on this page says that a mine is or is not under any particular property. Do not buy, sell, move, or make any decision about a home or about your safety on this alone. Ask the state mine map office named here for the maps, and have a qualified engineer look at the ground.
