English: A reconstruction of a ceramic beaker from the Cahokia Mounds site near Collinsville, Illinois. The engraving on the beaker is thought to represent a timber circle woodhenge. Beaker is reconstructed from a ceramic fragment with the design and similar shaped whole beakers. This sort of beaker has been shown to have connections to Black Drink Ceremonialism, as several examples have been shown through analysis of chemical compounds in residue left on the inside of the containers to have been used for the beverage.
