Stearns Quarry was a limestone quarry in the Bridgeport neighborhood in Chicago. It closed around 1970 and became a clean construction landfill. The Chicago Park District turned it into a very scenic and welcoming park, named Palmisano Park, in 2009. Here's the link for more information on this park.
