No experience is required. The barite crystals are found in relatively soft clay layers, making this a fun and accessible activity for beginners, hobbyists, and families alike. Children of any age are absolutely welcome but must be supervised by an adult at all times.
This specific site is world-famous among collectors for producing distinct, blade-like crystal clusters with a unique, pale sky-blue hue that is highly sought after in the mineral community.
A 4WD vehicle is not strictly required, but high-clearance vehicles are highly recommended. The dirt roads leading to the claim can become rugged, rutted, or muddy depending on recent mountain weather.
Yes. Your surface digging fee covers all the personal mineral specimens you dig up and harvest during your visit. There is a 20 pound limit on the amount of rock or material a participant may remove and take with them. Commercial mining or heavy mechanized equipment is strictly prohibited.
We recommend leaving pets at home. The high-altitude sun, sharp rocks, and lack of shade can be hazardous for animals, and pets must never be left unattended in vehicles.
Digs are weather dependent. Summer thunderstorms can roll in quickly in South Park. The clay at the site turns into sticky mud when wet, so if there is heavy rain or lightning in the area we recommend packing up for the day for your safety. Heavy snow, frozen ground, or severe spring mud will close the claim. Always call ahead to check current digging conditions (719)836-2458.
The rock-hounding site is a natural, undeveloped area with no restrooms or other developed facilities. There are no trash cans so please pack out all trash. Please bring water, snacks, sunscreen, appropriate clothing, and your digging tools.


Online payment through Paypal OR pay for your dig session directly at the Bayou Salado Trading Post. If paying online, print receipt & show to staff member at the post.
