Chaco!

So this is your introduction to Chaco Culture Natural Historical Park. It is located about three hours northwest of Albuquerque, in the middle of the desert, which is one of its attractions. It consists of an enormous number of Pueblo ruins built between 850 A.D. and 1250 A.D. I believe the current understanding is that it was a major center of ancestral Puebloan culture. There are roads leading to and from here that go for hundreds of miles. This is Chetro Ketl, and you can see that it is located near the base of the cliff on one side of the canyon.
