Northeastern California is a world-renowned destination for rockhounds, and the Warner Mountains of Modoc National Forest hold one of the largest concentrations of volcanic obsidian in the world. Specifically, the areas around Lassen Creek and Davis Creek north of Alturas attract visitors from across the globe looking for beautiful varieties of obsidian, including rainbow, gold sheen, silver sheen, and electric blue.
Understanding the Obsidian Mines
The U.S. Forest Service manages four designated obsidian collection mines in the Davis Creek area: Pink Lady, Rainbow, Middle Fork, and Davis Creek. Collecting obsidian for personal, non-commercial use is allowed, but visitors must obtain a free collection permit and follow strict safety guidelines.
How to Plan Your Rockhounding Trip
- Get Your Permit: Stop by the Modoc National Forest Supervisor Office in Alturas or print a permit online before heading to the mines.
- Wear Protection: Obsidian is volcanic glass and is incredibly sharp. Heavy work gloves, safety goggles, and sturdy boots are mandatory.
- Carry the Right Tools: A small rock hammer, pry bar, bucket, and brushes are useful for extracting and cleaning specimens.
- Check Road Conditions: The mines are accessed via unpaved forest roads. Dry summer and autumn months are the best times to visit.
Pairing Your Adventure with Alturas Comforts
After a day of digging and collecting, head back into Alturas to clean your treasures. Grab a hot meal at a local Alturas restaurant, refill supplies, or book a room at one of the cozy lodging spots in Alturas to rest up for another day of high-desert exploration.
