I was a long time then in coming upon it, and I did not see it again until I saw it whole, suddenly there across the valley, as if in the birth of time the core of the earth had broken through its crust and the motion of the world was begun. It stands in motion, like certain timeless trees that aspire too much into the sky, and imposes an illusion on the land. There are things in nature which engender an awful quiet in the heart of man; Devils Tower is one of them. Man must account for it. He must never fail to explain such a thing to himself, or else he is estranged forever from the universe.
