It looks incredible in pictures. That's awesome that you got to see it! Did you go to Antelope Canyon and some of the lesser-known but still spectacular slot canyons around Page?
It is very impressive, and it was well worth the risk of getting lost in the desert. I didn't get to see Antelope Canyon, but I did see some of the other, less strictly managed ones. Very beautiful, but I wouldn't like to get stuck in one during a flash flood...I really need to come back to this part of the US, there was so much I didn't have time to see.
