NABSQNO 17T-565145-4530990. This unnamed double waterfall natural bridge has been eroded through Vanport limestone by a spring that drains into Hell Run, also known as Hells Hollow. It is located in McConnells Mill State Park, about 5 miles west of Portersville, Lawrence County, Pennsylvania. Access is via the Slippery Rock Gorge Trail which passes a few yards north of the arch. Two other similar waterfall natural bridges are also found along this trail. More information can be found at this park interpretive site.
