Solstice Project Our research continues to enrich studies of archaeology, archaeoastronomy, anthropology and Native American cultures

The Solstice Project is a non-profit organization dedicated to the study of the rich astronomical heritage of the ancient Chaco culture of the American Southwest. Founded in 1978 by Anna Sofaer, initial efforts focused on the study, documentation and preservation of the Sun Dagger site, a remarkable celestial calendar of the ancestral Pueblo Indians. Subsequent Solstice Project research and films have revealed that the Chaco culture's ceremonial architecture was built to align with the cycles of the sun and moon, and that the elaborately engineered Chaco Great North Road was constructed to commemorate celestial north.

Our fourth film, "From the Mind’s Eye" expands our groundbreaking research in Chaco Canyon to a global scale, drawing striking parallels between four ancient civilizations. Although separated by thousands of years and miles, each used architecture, geometry, and celestial alignments to unify sky and earth—creating monumental forms visible only from above or within the mind’s inner vision. Watch the exciting trailer on our website. (Scroll down the page to see the video.)
