“Southwestern Rock Calendars and Ancient Time Pieces”
Pima County Caviglia-Arivaca Branch Library at Old Arivaca Schoolhouse
Saturday May 10, 2014
“Southwestern Rock Calendars and Ancient Time Pieces” free presentation by archaeologist Allen Dart for Pima County Public Library’s Caviglia-Arivaca Branch at the Old Arivaca Schoolhouse, 17180 W. Fourth St. (1 block north of Main Street’s Arivaca Mercantile) in Arivaca, Arizona*
Native Americans in the Southwest developed sophisticated skills in astronomy and predicting the seasons, centuries before Old World peoples first entered the region. In this presentation archaeologist Allen Dart discusses the petroglyphs at Picture Rocks, the architecture of the “Great House” at Arizona’s Casa Grande Ruins, and other archaeological evidence of ancient southwestern astronomy and calendrical reckoning; and interprets how these discoveries may have related to ancient Native American rituals.
