Look at that picture. In the bottom right of the image, very small, you can see Pito and Chris. Yeah, Arches is amazing. I am not sure exactly how many arches they have but there are lots and lots, and some are really huge.
I can't go into the details here (even to the extent that I understand them, which I don't) about how the arches are formed, but perhaps wikipedia can shed some light?
Anyway, Arches is very near Canyonlands National Park and both are spectacular, but quite different. They are both near the town of Moab which has some interesting stories to tell too.
Definitely worth a visit!
