The World That Was/Ancient Civilization, Wisdom
About the Solstice Project. The Solstice Project, a non-profit group, was organized in 1978 to study, document, and preserve the remarkable Sun Dagger - a celestial calendar of the ancient Pueblo Indians.
It continues to study other achievements of ancient Southwestern cultures. At summer solstice in 1977, Anna Sofaer, now president of the Solstice Project, discovered the Sun Dagger on top of Fajada Butte in New Mexico's Chaco Canyon. The calendar marks, with precise light patterns, the summer and winter solstices, the spring and fall equinoxes, and the nineteen year cycle of the moon. The Solstice Project has presented its research on the Sun Dagger site in several scientific publications, including: Sofaer, A., Zinser, V. & Sinclair, R.M. (1979), "A Unique Solar Marking Construct," Science, 206, pp 283-291; and Sofaer, A., Sinclair, R.M. & Doggett, L.E. (1982), "Lunar Markings on Fajada Butte, Chaco Canyon, New Mexico," Archaeoastronomy in the New World, ed.
