Ruby Falls was discovered in 1928 by Leo Lambert, who named it after his wife, Ruby. The cave system and waterfall are part of the karst topography of the Cumberland Plateau, formed by the dissolution of soluble rocks like limestone over geological time. The falls are fed by a natural underground stream.
