Crystal Park

Crystal Park is a unique recreation area at an elevation of 7,800 feet in the Pioneer Mountains in southwest Montana. Crystal Park is open for day use only and has a fee per car. Facilities include 3 picnic sites with tables and grills, information signs, toilets, and a paved trail with benches and an overlook. The facilities are designed to be universally accessible.

Quartz crystals are scattered liberally through the decomposed granite of the unique 220-acre site that's been reserved by the Forest Service for the popular hobby of rockhounding. Quartz crystals are hexagonal (six-sided) prisms, with a pointed "face" at each end. The crystals found at Crystal Park can be clear, cloudy, white, gray or purple. They can be smaller than your little finger or up to several inches in diameter. Gray, purple and other colors are caused by minerals within the quartz. Gray crystals are known as "smoky" and the highly prized purple ones are called amethyst. Single crystals are most common at Crystal Park. Most of the crystals have little value other than as collector's items.

Rules established for Crystal Park include a ban on tunneling. The rules are listed on signs and in brochures available at the site. Other rules include use of hand tools only, and a five-day-per-person season limit on digging.
