The Bozeman Gem and Mineral Club, organized in 1939, is the oldest “rock club” in Montana.
Club members have a wide range of interests including:

  • fossils
  • mineral specimens
  • faceting
  • jewelry design
  • gemology
  • geology
  • and lapidary arts

Through the various Club programs, affiliations, and activities, we have fun, improve our knowledge and skills, and educate our youth and the public. We welcome you to join us in pursuing this great, wholesome family hobby.

Upcoming Events - 2019:

Club Meetings:   
  • October 15 - Sacajawea Middle School: 3525 S 3rd Ave., Bozeman, MT
  • November 19 - 6:00pm -Sacajawea Middle School: 3525 S 3rd Ave., Bozeman, MT
  • December 5 - Christmas Party - 5:30pm - Bozeman Senior Center
Meeting Changes:
The November, January and February meetings will be held at 6:00pm, instead of the usual 7:00pm. This allows us to finish up a little earlier in the evening during snow season. These meetings will also be held at the Sacajawea Middle School (3525 S 3rd Ave).   

Other Events:

Christmas Party: December 5 - 5:30pm at the Bozeman Senior Center (807 N. Tracy Ave., Bozeman MT). The club will provide the main dish of Ham and/or Turkey. We ask people to bring a pot-luck side dish or desert to share. Also please bring your own plate, utensils and beverage (no alcohol is allowed at the Senior Center). We expect a huge silent auction, a live auction, and lots of fun... Anyone can bring items for the silent or live auctions - and they don't need to be rock related. We often have items like homemade jams and jellies.


Miscellaneous Items


The Bozeman Gem & Mineral Club hosts an annual show in late Spring at the Gallatin County Fairgrounds.  The primary purpose of the show is to acquaint the general public with our hobby and share the beauty of, and fascination with, our displayed collections.  It is also a great place to meet other rockhounds, add to your collection from dealer offerings, and provide a variety of fun and inexpensive activities for young visitors.  An admission fee is usually charged non-members to cover the costs of putting on the show.  A successful show is the cooperative effort of all club members.


The Montana Council of Rock & Mineral Clubs: An association of Gem & Mineral clubs in the State, the Montana Council promotes interest in rockhounding through education of members, schools, and the general public about the hobby.  The Council also helps members stay informed regarding legislative and regulatory matters that impact field access and collecting. The Council makes most gem & mineral shows in the State possible; It owns, and makes available to member clubs, the showcases that are used for displays at the shows, and it provides the trailer to transport them.

The Northwest Federation of Mineralogical Societies: An association of rock clubs in Alaska, Idaho, Montana, Oregon, Utah and Washington, the Federation sponsors an annual show, hosted by a member club.  Members from throughout the clubs of the Federation participate in the Federation shows and clubs send delegates to the Federation business meetings held during the show. The NFMS also sponsors a variety of lapidary arts workshops and field collecting trips, and loans DVD and slide show presentations to member clubs for monthly meeting programs.

The American Federation of Mineralogical Societies:  An association of rock clubs throughout the United States, the American Federation, in cooperation with regional Federations, sponsors a variety of programs including the offering of student scholarships, education of members and the general public about rockhounding, and fostering international relations.
Belonging to these associations provides contact with rockhounds from around the state, region, and country, often leading to field trips to areas we might not otherwise be aware of.  It also brings guests from other areas to our club meetings with samples of materials from their area.  Our club has enjoyed guests from several states and foreign countries.


Club-owned or donated materials are displayed in the County Courthouse and often loaned for display to area museums.
Club-owned or loaned, gems and minerals are on display in the Montana case at the Gallatin Yellowstone Airport.



When weather permits, club members try to get in at least one field trip per month.  Most are one-day excursions to a collecting site for a particular material.  On past field trips, participants have collected garnets, petrified wood, tourmaline needles, rhyolite, jasper, agate, calcite, sapphires, corundum, and various varieties of quartz crystals (including amethyst). The club currently maintains 2 quartz mining claims in the Highlands area (SW of Whitehall) and in the Boulder Batholith.
As well as collecting opportunities, field trips provide a time to become better acquainted with fellow club members while sharing an enjoyable, and occasionally exciting, time.

Memberships are available to anyone interested. Many members start out knowing only two kinds of rocks: pretty ones and ugly ones. With the willing sharing of information and skills by seasoned members, new members quickly learn to identify various rocks, minerals, and gems – and learn how to use and display them.

Memberships are available to families or individuals. Annual dues include membership in the Montana Council of Rock & Mineral Clubs and The Northwest Federation of Mineralogical Societies (NFMS), The American Federation of Mineralogical Societies, and subscriptions to A Stone’s Throw (the club’s monthly newsletter), The Montana Council Reporter, and The Northwest Newsletter.

Memberships are due between November and the end of January for the new year. 

Memberships are     $10.00 per adult
                              $20.00 per family
Dues may be sent to our address or given to our Treasurer at a meeting.

Frequently Asked Questions

What are the directions to the July 20, 2013 picnic meeting location?   The 2014 location is still to be determined.

Drive South 19th St from north  or west until you reach the corner of S. 19th and Hyalite (Canyon) Road (Approx 5-6 miles south of Kagy or 1 mile east of Cottonwood). Turn south on Hyalite Rd as though you are heading for Hyalite Revervoir.  Turn at the second left-turning road -- Canyon Meadow Rd. (If you drive over a cattle guard on Hyalite Rd, you've just passed Canyon Meadow Rd and need to turn around). On Canyon Meadow Rd, go east to the end (cul-de-sac). Brownish house address is # 146 -- only a few houses on the street. Call Ken or Carol at 582-8752 if you are lost.

What should I consider bringing on a field trip?

List of tools and equipment for rock club field trips:    (updated 7/1/2012)

When going out for a day of rock-hounding, consider where we will be going and ask the trip leader what he/she suggests.  Some areas are very isolated, so come prepared with the basics. These include a backpack for carrying food and water, sunscreen, bug spray, and tools. Lunch is your choice – bring what you like; remember to bring some snacks and plenty of water. Other items you might want to include would be a small first-aid kit, toilet paper, sunscreen, bug spray, eyewash, and tweezers. Bear spray is a good option when hiking in the mountains. The right clothing can make the outing more enjoyable. Bringing a hat or vest in hunter orange or bright pink could be helpful as these colors make you easier to find in case of accident. Temperatures can change quickly, so layering is suggested and long sleeves, hats (especially wide-brimmed varieties) are a good option; sturdy hiking shoes, gloves, and raincoat or poncho. Water-soaked (evaporative-cooled) neck wraps on hot days. Walking sticks are also useful.

Please police the area you are leaving and take out any food wrappers or garbage.  We carry out what we carry in  -- plus rocks of course. 
Do not dig under living trees in the rootball or cut large roots of living trees.

Deciding which tools to bring depends on the outing and whether you will be hiking short or long distances. Driving directly to a site allows for the use of larger, heavier tools.  Hiking longer distances usually limits the amount of weight you want to carry. Members carry most of the tools with them in their vehicles, giving them the option to decide which tools they want to take to the collecting site.

Screens for sifting dirt and gravel.       Round screens (sets of two or three) available at our local rock store (Earth Treasures) or square screens you can build yourself
Containers.           One or more 5-gallon buckets for carrying any rocks you find
                             Plastic baggies and paper for wrapping individual or smaller specimens
                             Small shoe boxes for fragile specimens like fossils
Pick, shovel, crowbar and maul.      Consider a smaller version of the crowbar and shovel for longer hikes
Rock hammer.    Any tool that can help chip or break rock 
Smaller digging tools.          Trowels, small claw-like implements, chisels;  and screwdriver-like tools, crevicing tools,  or the handle of a cut off paint-roller  (ask John Usher). These latter 3 are good tools for probing cracks and small pockets
Knee pads or kneeling pad.      Helps when doing a lot of kneeling or digging close to the ground
Gold pan.            Just in case you find a good spot to try (you never know)
The club is always looking for more efficient and interesting new tools that make rock hounding easier and more enjoyable; so if you have suggestions for tools that are not on the list, please let us know.

What are the directions to our Club's #1 clear quartz crystal claim?

This claim in the Highlands area in the Beaverhead - Deerlodge National Forest is accessible for use only by active Club members.  Simply call or email Ken Zahn (406-582-8752) ( and directions will be provided. A 4x4 vehicle will be needed.
