Children and fun-loving adults can enjoy a day of crafts, stories and Native American skills on Sunday, May 17th at the Cahokia Mounds State Historic Site.  The free Kids Day activities run from 11 AM to 4 PM at the ancient site.  Activities include crafting flint arrowheads, making clay pinch pots, grinding corn and throwing spears with an atlatl spear-thrower.  Children can also play Native American games and learn to identify animal pelts and tracks.  Kids can get their face painted with native designs. A storyteller will enthrall the audience with Native American tales, and the Kahok Dancers present interpretive dances at 2 and 4 PM.  Kids Day is held outside but most activities will be moved into the Interpretive Center in case of inclement weather.  Operated by the Illinois Historic Preservation Agency, Cahokia Mounds preserves the huge mounds built as part of the largest prehistoric Native American city north of Mexico.  It has been named a World Heritage Site.  The Interpretive Center is open Wednesdays through Sundays, from 9 AM to 5 PM, and the grounds are open until dusk.  There is no admission fee but a donation of $7 for adults, $5 for seniors, $2 for students and $15 for families is suggested.   For more information, call 618-346-5160 or go to www.cahokiamounds.org.
