SUMMARY:"Cahokia in Chesterfield: The Sun\, Moon and Milky Way" at Collinsv
 ille Memorial Library
DESCRIPTION:"Cahokia in Chesterfield: The Sun\, Moon and Milky Way" is the 
 title of the free presentation by Mark Leach\, September 15\, at 6 pm\, at
  the Collinsville Memorial Library\, at the monthly meeting of the Cahokia
  Archaeological Society. The public is invited to attend.\n\nNearly 1000 y
 ears ago\, a vibrant community\, related to the great prehistoric city of 
 Cahokia\, filled the entire Chesterfield Valley west of St. Louis. This pl
 anned civic\, ceremonial\, and market center was constructed to reflect im
 portant celestial alignments of the sun\, moon\, and Milky Way. Excavation
 s and other research in a portion of the valley have revealed over 100\,00
 0 artifacts\, including some made from exotic material from the Gulf of Me
 xico and the Great Lakes\, as well as three temples and two earthen pyrami
 ds that formed a solar calendar that stretched over 3.5 miles across the v
 alley. Leach will discuss these findings and others from over 70 years of 
 archaeological research\, which still is ongoing. Leach\, a local author\,
  has published several archaeological books\, including one with the same 
 title as his presentation\, and Chesterfield's Ancient Past\, and The Grea
 t Pyramids of St. Louis: An Ancient Metropolis.
