Annasazi or “Ancient Ones” arrived here in 800AD and progressively upgraded their way of life so that by 1200AD they had extensive agriculture and Brick villages established all around this very high altitude area. No one seems to know why they built in such a way as it appears they had no enemies. Their way of life came to an end because the fertility of the soils was totally repleted and so they could no longer sustain themselves. These ancient ruins are now an integral part of the world’s wonders and as such are an incredible place to visit.
