The wide variety of artifacts found in Chaco Canyon from the Anasazi era is impressive. Especially when you consider the major sites were likely looted several times over hundreds of years before archaeologists were able to conduct a proper survey.
One of the most intriguing and most important finds were the presence of skulls and skeletons of Scarlet Macaws, traded from hundreds of miles south. Like turquoise and chocolate, they were likely prized trade goods, and their perceived wealth may have contributed to a stratified societal hierarchy.
In the Chaco Canyon video game / computer simulation, one of the treasures you may find during your virtual archaeological dig is a 3D replica of a Scarlet Macaw skull, found in Pueblo Bonito by researchers from the American Museum of Natural History in 1897.
