Membership in the Central Oregon Geoscience Society is open to everyone, ranging from people who have a professional interest in geology to those with a casual interest. All of our presentations are free to the public, with a suggested donation for non-members. Field trips are open to members only, or guests of members.
Your membership contribution supports our regular programs, including monthly presentations, field trips, and educational outreach.
