In the southwest United States, high altitudes, open vistas, and cloudless skies create a visual atmosphere where the light is legendary. I focus on the role of light for the people of Chaco Canyon—a 1,000-year-old pilgrimage centre in the San Juan Basin of northwest New Mexico. Here, worldviews and cosmologies involved the dualistic juxtaposition of light and dark, visible and invisible, sun and moon. The movements of celestial bodies in a clear sky, and the presence of open sightlines with distinctive peaks, contributed to the creation of a complex cosmography. Sun and moon, visibility and invisibility, light and darkness opposed one another and revolved around Chaco Canyon—the centre of the ancient Chacoan world.
