Somerset serves as the focal point for this 1915 survey of the Pennsylvania highlands, where the local economy transitioned between agriculture and heavy industry. The landscape is defined by the prominent Laurel Ridge, which creates a natural barrier between Westmoreland and Somerset counties. Transportation through this difficult terrain was facilitated by the Pittsburgh and Philadelphia Turnpike and the Pittsburgh Westmoreland and Somerset RR, which followed the winding paths of Loyalhanna Creek and Quemahoning Creek.
