There are a lot of pictures you can look up. But they've endured really well since they're so high up on cliff faces. They're just kinda creepy because they are extremely old and the Anasazi did basically disappear. That could be for a number of reasons, they could have built so defensively because of warring tribes and were eventually just killed off or assimilated. It's true that there is a lot of superstition behind them and they were enemies of the Navajo. The word Anasazi can translate to "ancient people", "Navajo enemy", or "old stranger" so some people think they could have been aliens or at least abducted by aliens which is obviously ridiculous.
Anyway, it can be a little eery when thinking about the mystery surrounding them and seeing their nearly perfect structures. Plus, that part of the country can feel very empty and isolated, I can absolutely understand how people can be very superstitious out there.
