I went back to Monument Valley again today and again I still think it's an awe inspiring place. I'm usually too jaundiced to be that impressed by things, but that place was something else. I'm not sure that I'll go back in a while though, because I don't want to lose that feeling of awe about the place.

After that, Canyon de Chelly was a bit of a come down. It was impressive, but wasn't as striking as Monument Valley. If you're going to both, I'd recommend you start with the Canyon.
