The Colorado Archaeological Society is a private, non-profit organization established in 1935, and currently includes 9 chapters located throughout the state. The membership is comprised of avocationalists, students, and professionals interested in archaeology as well as the discovery, documentation, and protection of Colorado’s historic and prehistoric cultural resources.

Membership is open to any person interested in archaeology.


Membership in the Colorado Archaeological Society is processed through the State organization and processed through our membership portal.  When completing the membership form, you will be asked to select the chapter (primary chapter) you want to belong to.  At the same time you may select a secondary chapter to belong to at a lesser membership fee.  To assist you in your chapter selection visit our State CAS website which includes a map and description of the chapters. From there you can also access the membership portal.
