Where collection is allowed
The operator authorizes paid collectors to search its marked mine property during business hours and publishes a vehicle-load maximum.
Sign in and pay before entering. Facilities are primitive—portable toilets, picnic tables, and no running water—so bring supplies and confirm hours before a long drive.
Tools, limits, and timing
Tools and methods
The operator lists hand tools such as screwdrivers, shovels, rakes, hammers, and picks. Follow all marked no-dig zones and never throw rocks in the pit.
Amount and use
Current operator limit is one car or truck load; no trailers. Collection must occur during paid daytime access.
Season and current status
Hours and opening days can change. Call or use the operator’s current page before travel, especially after heavy weather.
Rules to confirm at the site
- Sign in and pay before collecting.
- Dig only where the operator allows.
- No night digging or trailers.
- Wear a shirt and closed shoes; supervise children.
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 veins and weathered crystal-bearing material can produce clear, smoky, amethyst-colored, and iron-coated specimens.
Surface staining can imitate internal color, so clean and test conservatively before naming a variety.
