I was reading about Chaco Canyon prehistory today and got to thinking: when was it we were there? Turns out: almost exactly a decade ago. Here’s a very large kiva, not sure where.
Pretty sure these are some of the rooms back against the cliff at Chetro Ketl. When were these places in use? About a thousand years ago. And still amazing.
These are scanned slide images (thank you, Guru). A different modern time, too.
