In Pittsburgh, the elevation varies wildly, fluctuating 660 feet from highest to lowest points throughout the area and making it one of the hilliest cities in the United States. Throughout this unruly and physically challenging landscape, the city's first mass transportation system was built - a steadily expanding network of public stairways, locally referred to as city steps, these flights of stairs are a throwback to a very different time in history and a very different Pittsburgh. Authors Laura Zurowski, Charles Succop and Matthew Jacob present the history of the Steel City steps and a walking guide to their scenic locations today.
