About

“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!

Agates of the Paleozoic Era

June’s presentation is on agates formed in the Pennsylvanian Limestone 245–300 million years ago during the Paleozoic Era. The focus is on Bear Canyon, Dryhead, HooDoo, Teepee Canyon, Fairburn, and others. Come see beautiful specimens of these agates and learn where they can be found.

Doug True and his wife, Jeanette, are longtime members of the Billings Gem and Mineral Club. Doug has held various leadership positions in the American Federation of Mineralogical Societies, American Land Access Association, and the Northwest Federation of Mineralogical Societies, in addition to our local club. He is a well-known expert on agates, minerals, fossils, and geology in general.
