NABSQNO 12S-671450-3953306. Black Rock Natural Bridge is an old waterfall natural bridge cut into Permian conglomerate by a tributary of Black Creek on the Navajo Nation, Arizona. Since the waterfall that created it has retreated out of linear sight, it should be considered old.
Black Rock Natural Bridge has a span of 49 feet, a height of 14 feet, a width of 14 feet, and a thickness of 2.5 feet. The services of a guide must be obtained by non-Navajos to visit this natural arch. It is located about 4 miles northwest of Window Rock, Arizona, the capital of the Navajo Nation.
