Jane; The salt mine is located on Whiskey Island near downtown Cleveland.Another salt mine is located at Painesville, about 30 miles east of Cleveland. It was owned by the Morton people. Also, a blue shale mine is in Valley View. The shale is used in aquariums,pool tables,etc. Cleveland was called the best location in the nation back then, for a good reason.If one got laid off at a factory, he could work the mines !! Shelby
