" The English novelist J. B. Priestley once said that if he were an American, he would make the final test of whatever men chose to do in art, business, or politics a comparison with the Grand Canyon. He believed that whatever was false and ephemeral would be exposed for what it was when set against that mass of geology and light. Priestley was British, but he had placed his finger on an abiding American truth: the notion that the canyon stands as one of our most important touchstones—a kind of roofless tabernacle whose significance is both natural and national. It is our cathedral in the desert, and the word our is key because although the canyon belongs to the entire world, we, as Americans, belong particularly to it. "
