Monthly Meetings

We hold monthly luncheon meetings on the third Wednesday of each month, October through May. Luncheon costs are $30 and students are free through our generous sponsors. RSVP is required – contact arrangements@ccgo.org or contact Wes Gisler at 830-239-4651 to make a reservation.


Our monthly bulletin is free as a downloadable PDF. A hard copy, mailed subscription is $60 per year. Details on our monthly meeting are published on the bulletin. Members receive bulletin and event reminders via email.


Society dues are $25. Students studying earth sciences and younger students may join for free. Download and mail (or email) an application to membership@ccgo.org. We will contact you to confirm and secure payment (or you can pay dues at our meetings.) Questions? Contact Randy Bissell at 361-885-0110.
