There are some pretty big buildings in there! Apparently the site (the Mummy Cave ruins in the Canyon de Chelly park) consists of about 70 rooms between the different buildings. Not sure how many buildings there are, I can see three distinct ones in this pic but since only one of them is still mostly standing I can imagine there are others than are harder to see

It’s Tse yaa Kin (“house under the rock”), known as Mummy Cave, in Canyon del Muerto. The most recent ruins are ~700 years old; the oldest archeological traces could be ~1700 years old.

Yeah this is just those natural forming multi story houses.

For anyone who can’t see, there’s an entire city under the cliff in the shade.
