Where to begin? One of the places we have been to in the last two weeks is Canyon de Chelley. It is Navajo land, considered sacred, and entrance to the canyon is restricted. You can take a tour to see some of the ruins of the cliff dwellings. We viewed a couple from the rim of the canyon, which was a long way off. If you look closely at my pics you can see them.  Here are a couple of links you may find interesting.
