Where collection is allowed
The Beaverhead-Deerlodge National Forest expressly permits hand digging inside the posted Crystal Park collection area after payment of the current recreation fee.
Paved routes reach the parking area, followed by a short walk. The site provides toilets, picnic facilities, a hand-pump well, and an accessible trail, but overnight camping is not allowed at Crystal Park.
Tools, limits, and timing
Tools and methods
Hand tools only. No tunneling, unsafe holes, overhanging banks, digging beneath trees, or excavation within five feet of trails, parking, signs, toilets, fences, and other facilities.
Amount and use
No commercial digging. The Forest Service limits digging to five days per person per season; current posted rules and fees control.
Season and current status
Normally open from late May through late October, sunrise to sunset, depending on snow and road conditions.
Rules to confirm at the site
- Pay the current day-use fee.
- Dig only inside the kiosk-mapped area.
- Keep excavations stable and free of overhangs.
- Keep dogs leashed and pack out all waste.
An old webpage, saved map, app layer, social post, or prior visit cannot override a current closure, posted boundary, permit condition, mining claim, staff instruction, or landowner decision.
What makes the site geologically useful
Quartz crystallized in veins and cavities as the Pioneer Batholith cooled roughly 72 million years ago.
Weathering later freed clear, milky, smoky, and occasionally purple quartz from the granite.
A low-impact trip plan
