Ad Hoc Tumbling Group
A Special GMS Group
for People Interested in Tumbling Rocks
The Ad Hoc Tumbling Group Meets
Third Tuesday
Every Other Month
Many people, young and old, begin their rockhound journeys by tumbling stones. It is a great way to get into the hobby and there is so much to learn from tumbling.
The GMS Ad Hoc Tumbling Group meets every other month via Zoom to talk about all things tumbling. If you are interested, you must be a member of GMS, and all members are encouraged to submit ideas for topics to cover.
The group also sponsors and runs an annual rock tumbling contest for novice and experienced tumblers. Winners are announced at our annual Mother's Day Weekend Rock Show.

Wow!! Where has the summer gone? The Tumbling Group has had some great speakers this summer, with Charles Carter talking about cleaning your stones before tumbling and Diana Poppelreuter talking about Wire Wrapping your tumbled stones. Thank you for taking the time to share your knowledge with the group. We will not have a meeting in August, because starting in September we will meet every other month on the third Tuesday. At the September meeting, we plan to announce the 2025 Tumbling Contest. We will cover the rules, as this coming year has a few changes. We will go in-depth about the stones being used in each division and give some background on the stones. Mark your calendars for September 17th, 2024, and join us via Zoom for the details.
