Dunlap Creek winds through the heart of this Alleghany County landscape, carving a valley that has long served as a primary transportation corridor through the Appalachian ridges. The settlement at Callaghan sits at the junction of these historical routes, where the Midland Trl follows the water's path toward the western gap. This 2019 survey documents the enduring physical landmarks of the region, including the notable Humpback Covered Bridge and the nearby Mud Tunnel, reflecting the engineering required to navigate this terrain.
