Local record guide
Local profile
Algonquin, a place of 29,700 people, is in McHenry County. Court and property records sit with McHenry County, and birth and death certificates come from the State of Illinois. Algonquin's own offices are in the cards above, and our McHenry County page lists each county office.
Abandoned mine records
Where the workings are, and the office that holds the mine maps.
From the old mine records
The mine records hold 3 named mine sites inside the city or town limits, 2 of them worked out or abandoned; the old survey maps add 11 holes drawn inside the city or town limits, 0 of them shafts or tunnels. The mineral the records name is construction sand and gravel.
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.
Disclaimer: The mine information here is for general information only. Old mine records can be incomplete, outdated or wrong, and finding nothing here does not mean there is nothing there. 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.
