Somerset serves as the hub of this rural landscape, which transitioned from early mountain transport to a more complex rail-and-road network by the early 20th century. The topographic data reveals the steep grades of Laurel Ridge and Negro Mountain, barriers that shaped the passage of the Pittsburgh and Philadelphia Road and the Baltimore and Stoystown Road. Regional connectivity is further evidenced by the industrial footprint of the Pittsburgh Westmoreland and Somerset RR and the Quemahoning Tunnel.
