We recently transitioned our membership payment and management platform away from the Mineralogical Society of America (MSA) and are now using the online platform WildApricot. Through this system, we will be able to track membership status and send communications regarding upcoming GSW events.
Please click the link below to join or renew your membership, and establish a membership account with WildApricot:
GeologicalSocietyofWashington.wildapricot.org
Your username will be the email address entered to establish your account. A password is not automatically assigned when you first sign up. To set an account password, click on “Forgot Password” when prompted to login, and a link to set your password will be sent to the email address provided.
Current and lapsed members of the GSW will receive an email renewal notification from GeologicalSocietyOfWashington@wildapricot.org.
If you believe you are a current or lapsed member but have not received an email, or you have questions regarding the new membership platform, please contact:
membership@gswweb.org
NOTE: You still have the option of sending in your membership dues by check, by mailing them to Geological Society of Washington, Inc., P.O. Box 382, Rockville, MD 20848. If you choose to pay by check, simply sign up at the membership level you desire without submitting an online payment, and we will clear the payment on the back-end when we receive the check.
Business Mailing Address (new as of September, 2025):
Geological Society of Washington, Inc.
