Yeah,IIRC that book first introduced me to the SW tribes’ peaceful habit of slaughtering people and eating the marrow from their bones.
Scary stuff, when one considers it carefully!
The last time I visited Mesa Verde NP the exhibits and interpretation were in the full flush of the revisionist reaction to the original and perfectly logical assumption that the cliff dwellings were defensive in nature. Lots of idiotic claims that they were some sort of passive solar installations and such. And how could the peaceful Anasazi possibly have any need for defense?
Since then they have found definitive proof of cannibalism, and quite possibly of cultural influence from the south (Mexico) leading to torture, human sacrifice in addition.
Hey, if some of the neighbors started going in for Aztec-type practices, I’d move up on a cliff myself!
