NABSQNO 12S-671450-3953306. Black Rock Natural Bridge is an adult waterfall natural bridge formed when a harder layer of Shinarump conglomerate was undercut by a tributary of Black Creek. It is located about 3 miles southwest of Fort Defiance, Apache County, Arizona. Because this area is part of the Navajo Nation, visitors must be accompanied by an authorized guide. Black Rock Natural Bridge has a span of 49 feet. Unfortunately, thoughtless vandals have marred this historic landmark with several spray-painted graffiti. It is listed in the Vreeland catalog as number 11-18. Another photo and additional information is found here.
