Kings living in palaces may have ruled New México's Chaco Canyon a thousand years ago, causing Pueblo people to reject the brawny, top-down politics in the centuries that followed, according to a University of Colorado at Boulder archaeologist.

University of Colorado Museum anthropology Curator Steve Lekson, who has studied Chaco Canyon for several decades, said one argument for royalty comes from the rich, crypt-style burials of two men discovered deep in a Chaco Canyon "great house" known as Pueblo Bonito several decades ago.  They were interred about A.D. 1050 with a wealth of burial goods in Pueblo Bonito, a 600-room, four-story structure that was considered to be the center of the Chaco world, he said.

Archaeologists have long been in awe of the manpower required to build Chaco's elaborate structures and road systems, which required laborious masonry work, extended excavation and the transport of staggering amounts of lumber from forests 50 miles distant, he said.  The scale of the architecture and backbreaking work undertaken for several centuries suggests a powerful centralized authority, said Lekson, curator of anthropology at the University of Colorado Museum.

Located in northern New Mexico, Chaco Canyon was the hub of the Pueblo culture from about A.D. 850 to 1150 and is believed to have held political sway over an area twice the size of present-day Ohio.  A center of ceremony and trade, the canyon is marked by 11 great houses oriented in solar, lunar and cardinal directions with roads that appear to have connected Chaco to outlying Pueblo communities.

Researchers have long pondered how Chaco rulers wielded control over outlying Pueblo communities in present day Utah, Arizona and Colorado, he said.  Such "outliers," located up to 150 miles away, would have required that visitors from Chaco walk up to eight days straight in order to reach them, ...
