The Pine Creek Gorge National Natural Landmark includes Colton Point and Leonard Harrison State Parks and parts of the Tioga State Forest along of Pine Creek between Ansonia and Blackwell. This federal program does not provide any extra protection beyond that offered by the land owner. The National Park Service's designation of the gorge as a National Natural Landmark notes that it "contains superlative scenery, geological and ecological value, and is one of the finest examples of a deep gorge in the eastern United States."
