I certainly hope that the new owners are going to guard this site. When I think of how places like Chaco Canyon were treated by pot stealers and amateur archeologists.
Lots of good reading about Chaco Canyon and the Anasazi legends of the Great Gambler. Some archeologists believe Chaco Canyon (especially the Pueblo Bonito area) was one of the first Indian gaming casinos. The Hopi, Zuni,and Navajo peoples won't allow casino gambling on their lands due to the legends of an evil man spirit sometimes called Noqoilpi or "He-Who-Wins-You-Over."
Some Southwestern legends tell of people from that era living in hidden places then dropping everything (baskets, beads, pots) to flee from the Great Gambler and his thugs.
One of my Navajo friends tells me a casino referendum vote is coming up, so it may not be long before that tribe breaks its ancient taboo against gambling. Well, Noqoilpi did say after he lost a major bet and got thrown back up into the stars that he would return some day.
