The astonishing discovery of an ancient celestial calendar in Chaco Canyon, NM.

The Sun Dagger

This classic, timeless film documents the extraordinary celestial calendar created by ancient North American Indians, and rediscovered by artist Anna Soafer, high on a butte in New Mexico.

The 'dagger' is presently the only known site in the world that marks the extreme positions of both the sun and moon.

The film explores the complex culture of the Anasazi Indians who constructed the calendar, and thrived both spiritually and materially in the harsh environment of Chaco Canyon a thousand years ago.

'It changes forever history's perceptions of America's early Indian colonists. And as an astronomical and geometrical marvel, it ranks with the Pyramids and Stonehenge.' Science 84

'THE SUN DAGGER is a 'must-buy' for school districts and public libraries.' Media and Methods

'The multidisciplinary nature of this film makes it possible to use it in many classroom situations. The excellent teaching guide, written by Don Reid, vastly improves the film's instructional value.' Journal of College Science Teaching

'Both (versions) are excellent.' Editor's Choice, Science Books and Films
