Natural Bridge (Virginia)
Natural Bridge in Rockbridge County, Virginia is a geological formation in which Cedar Creek (a small tributary of the James River) has carved out a gorge of the limestone mountainous terrain, forming an arch 215 ft (66 m) high with a span of 90 ft (27 m). It consists of horizontal limestone strata, and is the remains of the roof of a cave or tunnel through which the creek once flowed.
