Tuscarora Mountain and Cove Mountain dominate this landscape in South Central Pennsylvania, carving out a series of narrow valleys where local industry and transportation networks took root by the late 20th century. The village of Richmond Furnace and the community of Fort Loudon highlight the region's historical industrial ties, while the Old Railroad Grade and Old RR Grade trace the legacy of mountain-spanning transport.
