Lol. Well, to be fair, I'm not sure they would've existed yet, either. The ancestors of them & the Navajo wandered down to the Grand Canyon area during the time of the Anasazi Culture, then broke off & became their own thing, I want to say, in the 1300s. Honestly, my knowledge set is mostly Eastern US & Canada. The further west you go, the less I have to go on, so I may be wrong on the dating of that.
