From the Wikipedia article

The Standing Stone Trail is an 84.2-mile (135.5 km) linear hiking trail in south-central Pennsylvania, leading from Cowans Gap State Park in Fulton County, north to Detweiler Run Natural Area in Huntingdon County. Most of the trail follows rocky ridgetops in the Appalachian Mountains, with some walking through agricultural valleys and small towns, and it also passes through various segments of Rothrock State Forest and four different State Game Lands. It was constructed to connect the Tuscarora Trail and Mid State Trail, and it is a component of the Great Eastern Trail network.
