The Solstice Project's investigations at Chaco Canyon since 1977 changed forever our picture of the ancient people who built that amazing complex--and why they did it. New light on the solstice markers, lunar and solar alignments, and insights into the enigmatic Chaco roads system are revealed in the nine important and richly illustrated papers in Chaco Astronomy: An Ancient American Cosmology.
Anna Sofaer, who encountered the now-famous "Sun Dagger" site in 1977, has pursued Chaco's cosmological enigmas for the past 30 years with remarkable determination, intelligence and insight. The Solstice Project she created has drawn an impressive gathering of talented researchers in several key disciplines. Here is the substance of their surprising findings.
