Over the past quarter century, a new field of study called archeoastronomy has developed, investigating astronomical alignments that may have been incorporated or utilized in prehistoric times by ancient people. Years of field research at petroform sites may prove that some of the most unique and oldest archeoastronomy sites in North America - possibly as old as the pyramids in Egypt - are located in southeastern Wisconsin. Join us to learn more about this fascinating topic as independent researcher and amateur astronomer (46 years) Herman Bender discusses Prehistoric Astronomy In The Upper Midwest. This event is held in conjunction with The Ann Arbor/Ypsilanti Reads 2009, which, this year focuses on the theme The Universe: Yours To Discover.
