“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!

Crystal Park & Calvert Mine

Trip Host: Greg Thorson

Places we will be huntng: Crystal Park(15 Aug), Calvert Mine(16 Aug), and possibly 1 or 2 other locatons(17th)

What will we be huntng for??
Crystal Park: Clear, Smoky and Amethyst Crystals.?
Calvert Mine: Epidote, Smoky Quartz, Garnet, and Aquamarine.

A meeting point will be chosen and carpools established once we get a list of attendees. Meetng time will be 8:00 am each morning. Those that want to come later are welcome to meet the larger group at the field sites on their own time. Note that there is a $5/Vehicle fee per day in Crystal Park so please plan accordingly. Please pack snacks, a lunch, and lots of drinks. The field trip will last until the late acernoon(3-4pm).

This trip will be near Dillon, MT. There are many hotels and restaurants in the Dillon area for those wanting to use commercial accommodations. For those with campers or tents, there are several campgrounds in the area, to include the Grasshopper, Price Creek, and Mono Creek campgrounds. I will be staying in a campground, most likely the Grasshopper Campground (assuming availability). No food/lodging/transportion will be provided by the club. You are on your own to make campground or hotel reservations and for transport to and from the Crystal Park area.

Access to the Calvert mine and Crystal park are via good roads so 4x4 is not required. Walking/ hiking will be required to get to the digging locations. Minerals/crystals at these locations are found in the ground. Please bring your own shovels, picks, rakes, and buckets for digging. This site should be good for all ages if you are willing to dig.

The weather should be hot and dry, but it is Montana so please check the weather before you pack for the trip. It most likely will be hot and sunny so please dress appropriately, wear a hat, bring sunscreen, bug spray, and lots of water.

Dousing for Minerals & Water

Adrie Min, a member of the Rimrock Dousers, will be speaking on the ancient art of dousing for minerals and water. He has known numerous Montanans that have used dousing in their search for gold. He will have handouts and members can try their skill at finding a mineral of some kind. Maybe someone has some gold nuggets to borrow!

Adrie was raised in Holland but has lived in Ryegate, Montana for more than 25 years and is a very proud U.S. citizen. He is a physical therapist at Wheatland Memorial Healthcare.
