"The Walnut Canyon National Monument was the ancient home of the Sinagua people, whose dwelling areas you can still explore. These ruins are not nearly as sophisticated as what you will see at Wupatki, but it is still a marvel of the human spirit that anyone lived in such a dry area. In fact, Sinagua means “without water” in Spanish."
