Monument Valley: red to blue; great violent shadows, planes and prisms of light. Once, from a window in the wall of a canyon, I saw men on horseback, far below, two of them, moving slowly into the gloaming, and they were singing. They were so far away that I could only barely see them, and their small, clear voices lay very lightly and for a long time on the distance between us.
The valley is vast. When you look out over it, it does not occur to you that there is an end to it. You see the monoliths that stand away in space, and you imagine that you have come upon eternity. They do not appear to exist in time. You think: I see that time comes to an end on this side of the rock, and on the other side there is nothing forever. I believe that only in diné bizaad, the Navajo language, which is endless, can this place be described, or even indicated in its true character. Just there is the center of an intricate geology, a whole and unique landscape which includes Utah, Colorado, Arizona, and New Mexico. The most brilliant colors in the earth are there, I believe, and the most beautiful and extraordinary land forms - and surely the coldest, clearest air, which is run through with pure light.
