The Black Diamond Mines Regional Preserve includes the remains of several coal and sand mines and the sites of five long gone coal mining towns (Nortonville, Somersville, Stewartville, West Hartley and Judsonville). Safe sections of the mines can be toured on a guided tour. Importantly, do not attempt to enter any of the mines without a guide. (Though, this would be difficult as gates have been installed on all entrances.) Some of the coal seams are still offgassing, and deaths from hypoxia have occurred in the recent past when the abandoned mines were a party spot for local kids. Also within the park is Rose Hill cemetery.
