Mill Creek chert
From Wikipedia, the free encyclopedia
Mill Creek chert is a type of chert found in Southern Illinois and heavily exploited by members of the Mississippian culture (800 to 1600 CE).[1] Artifacts made from this material are found in archaeological sites throughout the American Midwest and Southeast. It is named for a village and stream near the quarries, Mill Creek, Illinois and Mill Creek, a tributary of the Cache River.[2] The chert was used extensively for the production of utilitarian tools such as hoes and spades, and for polished ceremonial objects such as bifaces, spatulate celts and maces.
