The remarkable forces of erosion created this 2,000 mile spectable in Arizona. And they are still at work today, sculpting monumental scenery & natural habitat that is alive with the varied wildlife that call the canyon home. The immensity of the Grand Canyon is profoundly moving, & its effect was not lost on Theodore Roosevelt when he established it as a parkland in 1908. Beginning with Major John Wesley Powell's explorations, the historical background of this video is enriched by a never before filmed sequence of Shaman's Gallery - a significant find of rock paintings created by the Anasazi (Ancient Ones) - dating between 2000 B.C.-A.D. 1. The canyon's astonishing story, profound beauty, diverse wildlife & magic light show are captured.
