At the summer solstice in 1977, Anna Sofaer rediscovered the Sun Dagger site in Chaco Canyon, New Mexico. Following this finding, Sofaer founded the non-profit Solstice Project – an interdisciplinary team of astronomers, archaeologists, anthropologists, architects, computer animators, and remote sensing experts – and has conducted three decades of research at Chaco. She has produced, directed, and co-written two documentaries The Sun Dagger and The Mystery of Chaco Canyon, both narrated by Robert Redford and broadcast nationally by PBS. Her work has been published in nine scientific papers, republished in the book Chaco Astronomy: An Ancient American Cosmology. Currently, Sofaer is producing and co-directing a third documentary titled Written on the Landscape: Mysteries Beyond Chaco Canyon.
