A Sense of Size, Grand Canyon, AZ 9-15
(1 in a multiple picture album)
Look closely and you'll see a man in a blue shirt in the lower center of the picture. He is likely pondering the size of the canyon. Think of this: the canyon continues on for 200 miles from where he is standing. The bottom of the canyon where the Colorado River flows is a miles below him. If he looks off to his right, he'll see the north rim which is ten miles away.
