Blue Mountain and Cove Mountain dominate this central Pennsylvania landscape, creating a series of parallel ridges that define the travel and settlement patterns of the early 1950s. The Appalachian Trail follows the crest of Blue Mountain, crossing the county line between Perry and Cumberland counties at high-elevation gaps like Millers Gap and Lambs Gap. This survey reveals a landscape of ridge-top forests and valley floor farming, where the winding Conodoguinet Creek and Sherman Creek provided the necessary water for early industrial sites such as Hustons Mill.
