From the rim of the Grand Canyon, which is the viewpoint in the composite photo, the major plateau in the canyon where Manhattan could sit is roughly 3,000 feet below. It's another 2,000 feet down to the narrow gorge of the Colorado river. The top of the spire of the Chrysler Building at 1,046 feet would be 2,000 feet BELOW the rim of the canyon, almost out of sight from this view. The top of the Burj Khalifa, the tallest building in the world at 2,722 feet would be 300 feet below the rim; unless the base was at the Colorado River, then it would be 2,300 feet below. It is indeed a Grand Canyon.
