In the Arizona desert, almost within sight of Phoenix, there is a site like these that has yet to be rediscovered. A nineteenth century military patrol found it and reported what it was. If they were correct and if it contains what they said it did, and if it has not been raided, it would be a priceless discovery. Some yahoo will stumble on it someday and either be a millionaire or an archaeological hero.
The patrol records are in the UNM library in Albuquerque. I keep thinking that I will stop by there and spend a day or two researching but I always forget or don't have the time.
