Cahokia Archaeological Society

The Cahokia Archaeological Society (CAS) was founded to unite and educate all persons interested in the archaeology of Illinois and Missouri, particularly the regions surrounding the great Cahokia mound group, for the purpose of:

  • Preserving the remains of the prehistoric and historic aboriginal peoples who once inhabited this area,
  • Encouraging and participating in the scientific investigation, study, and interpretation of these remains,
  • Fostering and arousing a constructive public attitude towards the archaeology of these States.

We meet on the third Thursday of every month.  Currently we are at the Collinsville Public Library, with a business meeting at 5:30 pm followed by presentation/program at 6:30 pm. Our presentations draw on in-house, local, and regional experts to inform and enlighten us. We are now streaming our monthly programs on Facebook live and archiving them to YouTube.

For more information, please find us on Facebook or YouTube

In cooperation with other organizations, such as the Cahokia Museum Society, Madison County Historical Society, we participate in numerous community activities. We normally have a potluck in June.
