Fajada Butte in Chaco Culture National Historical Park stands as a monument to the sophisticated celestial knowledge of the ancestral Puebloans. These native people inhabited what is now the American Southwest over a thousand years ago. Their understanding of solar and lunar cycles is evident at the butte. Carefully arranged stones on the cliffs cast shadows, or ‘sun daggers’, over spiral petroglyphs. These mark the passing of solstices and equinoxes, reflecting a complex timekeeping system. The Sun Dagger is more than a unique rock formation. It is a sophisticated astronomical marker. Its discovery in the 1970s opened a window into the lives of the Chacoans.
