We meet once a month for a business meeting, program and Show & Tell, and usually have a Kid's corner with special activities during the meetings. Guests are always welcome!

Fieldtrips are organized during the spring, summer and fall.

Our Annual Show includes 6-7 mineral/fossil dealers, 8-10 demonstrators, special program for Scouts to earn badges during the show, a swap for members to sell their finds, and silent auctions throughout the show.

The Club has a monthly newsletter - Centrill Gems- that is mailed or emailed to members.
