In the Grand Canyon, Arizona has a natural wonder which, so far as I know, is in kind absolutely unparalleled throughout the rest of the world. I want to ask you to do one thing in connection with it in your own interest and in the interest of the country--to keep this great wonder of nature as it now is.
Leave it as it is. You can not improve on it. The ages have been at work on it, and man can only mar it.
--Theodore Roosevelt
