A documentary narrated by Kieth Merrill. It is shown in the IMAX theater in Tusayan near the entrance of the Canyon. I like the opening line, "Man clings to the edge of eternity." The film focuses on human activity. The Anasazi were the first people in the Canyon. The Spaniards found it in 1540. John Wesley Powell, the one-armed Civil War veteran, navigated the Colorado River with his men in 1869. I was waiting for geology. It never came. The producers were aiming for a big screen experience and ticket sales rather than trying to impart knowledge. I wonder about the film's subtitle, The Hidden Secrets. It seems the secrets might be the fossils buried in the Canyon walls.
