"Grand Canyon Voyage is the record of how seven daring people in three tiny boats ran the Colorado River from Lee's Ferry in Arizona, through the awesome gorge of the Grand Canyon, to Lake Mead in Nevada. The trip itself was the exciting and gallant climax to four years of dedicated effort by Al Morton. Ideally, this film record of the trip should be infused with this same excitement, this same sense of gallant adventure. That it is not consistently so inspirited will be a source of sincere regret to all who know Mr. Morton. But perhaps no motion picture of this dangerous, demanding river run could recreate this spiritual overtone. The physical odds against filming were too great, too overwhelming, for controlled camera work and integrated continuity. Survival itself became more important than an image of it. Al Morton, we believe, has done a supremely difficult job far better than would the most of us. He has done it as well, surely, as any cameraman living." Movie Makers, Dec. 1951, 411.
