The site just west of the D&H Seventh Avenue crossing in Carbondale was the location of the first deep underground anthracite shaft mine in America. A monument marking the site originally stood there, but to protect it from destruction during the mine fire on Carbondale's West Side, Gillen Coal Company moved it in the early 1960's to its offices at 78 Cottage Street, where it remained for 10 to 12 years. It was then moved to the front of the Columbia Hose Company, formerly on the site where the Carbondale Public Library now stands, and later to a location on the Sixth Avenue side of the present grounds of the Carbondale Fire Department. In mid-October 2003, it was returned to its original position, and on October 24, 2003, it was unveiled there in ceremonies conducted by the City of Carbondale, the Carbondale Historical Society, the Chamber of Commerce, and the Anthracite Heritage Discovery Center, with Edward D. Yankovich, Jr., president of the United Mine Workers of America, taking part along with a broad range of city and state officials.
