註釋"Not only have geologists discovered the reasons for the majestic width and depth of the Canyon, they have found that at one time the Colorado River ran through it in the opposite direction. At another time, hundreds of feet of gravel buried an ancestor of today's Colorado River. Then erosion removed the gravel and resurrected the river, in what James Lawrence Powell has dubbed the Lazarus Theory." --Cover.
