I can tell that it's the old bridge on the left because of its laced members. I believe this photo is looking to the west because I remember the mountains on the east side of the canyon were more colorful.
Two young women were sitting under the shade of a tree selling jewelry by these bridges and I bought a silver pin in the shape of a roadrunner from them. I was happy because I made the women laugh by trying to speak Dine to them. The more I butchered their language the more they laughed.
