Lying on the border between Utah and Arizona, the valley is well-known for having been used in many films - most famously with John Wayne*. Notice how the clouds are tinged red - that's not a camera fault, it's reflection of the red soil!
This is Navajo Nation country and if you zoom in and look at the far left you can (just!) see a Hogan - one of their homes (where tourists are not to go without an invitation)
** It's possible to tour many parts of the valley in your car or on a tour with a guide or even on horseback. I've done it in an "ordinary" car and although it's rough and sandy in places it's not too difficult.
*MANY films have been made here - too many to mention, so I suggest looking here: en.wikipedia.org/wiki/List_of_appearances_of_Monument_Val...
