"Pine Creek Gorge, sometimes called The Grand Canyon of Pennsylvania, is a 47-mile (76 km) gorge carved by Pine Creek in Pennsylvania. It sits in about 160,000 acres (650 km2) of the Tioga State Forest. The canyon begins south of Ansonia, near Wellsboro, along U.S. Route 6 and continues south. Its deepest point is 1,450 feet (440 m) at Waterville, near the southern end. At Leonard Harrison and Colton Point State Parks, it is more than 800 feet (240 m) deep and the distance rim-to-rim is about 4,000 feet (1,200 m)."
