“We love mineralogy, geology, rockhounding, paleontology, lapidary arts — anything related to rocks! We are dedicated to learning, exploring, sharing, and educating others so they can enjoy earth science as much as we do.”

Club Meetings

We meet the first Thursday of each month. We enjoy an educational presentation by a guest speaker and sharing finds with fellow rockhounds.

Field Trips

We go on several single day and multi-day field trips each year — surface hunting or digging.

Rock Shows

Our annual rock show is the first weekend in May. There are other rock shows in Montana and Wyoming too!

2021 Rocks & Stuff Swap Meet

Buy, Sell or Swap just about anything… including rocks! Admission is free. Things you might find at the swap meet:

• Rocks (of course… the sponsors are rockhounds!)
• Jewelry
• Crafts
• Home-grown vegetables
• Mexican food
• and more!

If you want to display goods for sale or swap, rent a double-long parking space for only $20. Or rent two spaces for $35. Park your vehicle in the back space and display your goods in the front space.

You may sell or swap anything you want as long as it is legal, does not require a license, and is family-friendly. Bring your own tables and anything else you need. Nothing is provided except the space.

Contact Doug at (406) 670-0506 for more information or to reserve a parking space.

This is a fundraiser for the Billings Gem & Mineral Club, a non-profit organization.
