What Might You Find?
Quartz crystals may vary in size, shape, clarity, and color. Some are transparent, while others are cloudy or smoky.
Not every crystal will be perfectly formed, and finding good specimens often takes patience.

Crystal Park
Discover the geology, natural beauty, and quartz crystals of one of southwest Montana's distinctive destinations.
A HANDS-ON GEOLOGICAL EXPERIENCE
Discover Crystal Park
Located in the Pioneer Mountains of southwest Montana, Crystal Park is a designated public quartz crystal collecting area in the Beaverhead-Deerlodge National Forest.
Visitors can explore the collecting area and search for quartz crystals while enjoying the mountain environment. Crystal Park offers a rare opportunity to experience geology firsthand rather than simply viewing it from a distance.
THE SCIENCE BEHIND THE CRYSTALS
Why Are There Crystals Here?
The quartz crystals found at Crystal Park are associated with the geological history of the Pioneer Mountains, including the emplacement and subsequent weathering of granitic rocks.
Quartz is a mineral composed of silicon dioxide. Under suitable conditions, silica-bearing fluids can deposit quartz in spaces within rock, allowing crystals to grow over long periods of geological time.
How Quartz Crystals Form
As silica-bearing fluids cool or their chemistry changes, dissolved silica may crystallize. Where sufficient space is available, quartz can develop its recognizable six-sided crystal form and pointed terminations.
Later weathering and erosion can break down the surrounding rock and expose or release crystals, making them accessible near the surface.
Geology Connection
Crystal Park demonstrates how processes occurring deep within the Earth can eventually produce minerals that people discover at the surface.
What Makes Quartz Interesting?
Quartz is one of the most widespread minerals in Earth's continental crust. It has a hardness of 7 on the Mohs scale and occurs in many different geological environments.
Its crystal shape, durability, and variety of appearances make it especially popular with mineral collectors.
SEARCHING FOR QUARTZ
Finding Crystals at Crystal Park
Visitors search for crystals in the designated collecting area, where previous digging and natural weathering have exposed mineral-bearing material.
How to Search
Look carefully through loose material and areas where collecting is permitted. Small hand tools can be useful when allowed by current regulations.
Work carefully, respect other visitors, and avoid creating hazardous holes.
Useful Equipment
Sturdy footwear, work gloves, eye protection, drinking water, and a small container for specimens can make the experience more comfortable.
Collect Responsibly
Follow posted collecting limits and tool restrictions. Keep digging areas safe, pack out litter, and leave the surrounding forest undisturbed.
VISITOR INFORMATION

Before You Go
Check the current opening status, road conditions, collecting regulations, fees, and fire restrictions. Information on this page is educational and is not a substitute for official Forest Service guidance.
PROTECTING THE RESOURCE
Responsible Crystal Collecting
Crystal Park is a shared public resource. Responsible collecting helps preserve the experience for future generations.
Collect only within authorized areas, obey current limits and restrictions, and avoid damaging vegetation or creating unsafe excavations.
Because collecting rules and site conditions can change, always rely on the current regulations posted by the managing Forest Service district.
