The Cascade Mineralogical Society is a non-profit educational organization. Our club is a proud member of the Northwest Federation of Mineralogical Societies, the American Federation of Mineralogical Societies, and the Washington State Mineral Council.

We welcome individuals interested in geology, mineralogy, paleontology, gems, and related lapidary arts to join us. The club’s objective is to stimulate interest in studying the earth sciences, lapidary arts, and related subjects. These goals will be accomplished through educational presentations, personal experience, and demonstrations at club meetings and other public presentations. The club also provides opportunities for field trips, rock collecting, and social gatherings. We are located in Kent, WA.

You are welcome to join us as a guest – so check us out!  All are welcome, and membership is open to everyone.
