Native Americans in the US Southwest developed sophisticated skills in astronomy and predicting the seasons centuries before non-Native American peoples entered the region. In this presentation, Al Dart discusses archaeological settlement layouts, architecture, and petroglyphs in New Mexico, Arizona, Colorado, and Utah that provide evidence of ancient southwestern astronomy and calendrical reckoning.
