Sept - Oct meetings 2022

Next meeting: Monday, September 12, 2022
Doors open 6:30 p.m., program 7:00 p.m.


Our guest speaker will be Kris Rowe speaking about field trips, winter and what you should not do while rockhounding. Kris leads field trips in the Fresno area through his group Rockhound Field Trip Fanatics. Other rockhounds are invited to join his group and go on those field trips too. Who would not enjoy one more field trip or dreaming about Field Trips past and future before winter makes it difficult to impossible?
