Exploring Twin Springs Rockhounding Area at the Owyhee Lake

Twin Springs is one of the great rock collecting sites in Southeastern Oregon, located west of Owyhee Reservoir, approximately 20 miles southeast of Nyssa and 30 miles south of Vale.

The rugged, sagebrush-covered landscape is a heaven for rockhounds, offering a wealth of agate, jasper, petrified wood, chalcedony, calcite, and occasionally geodes. Minerals are widespread, with some areas being richer than others.

Agates of various sizes are plentiful here, available in clear, white, blue, or gray variations. They are often adorned with waterlines, mossy patterns, or intricate botryoidal and crystalline cavities.

Jasper is also abundant, ranging in colors from blue and green to gray and brown. The sizes vary widely, from small pieces suitable for tumbling to larger, solid chunks that can be cut and polished.

Float materials can be found throughout the sagebrush, dumps, dry washes, and hillsides. Begin with surface collecting to determine if a spot looks promising.

We stopped at three locations, but the last one was particularly rich with material. To reach these spots, a rugged 4WD high-clearance vehicle is recommended.

Exercise caution and respect any claim markers encountered to avoid trespassing.

Know Before You Go

The Twin Springs area is a remote desert destination that requires careful preparation. Here are essential tips to ensure a safe and enjoyable rockhounding.

There are no services available within 20-30 miles, including gas stations, drinking water, or cell phone reception. Plan accordingly and ensure your vehicle is fully fueled and stocked.

Rattlesnakes are common in the area. Stay vigilant and aware of your surroundings to avoid encounters.

Do not attempt to visit during rainy conditions or when roads are wet. The terrain can become treacherous, making travel difficult and potentially dangerous.

A rugged 4WD high-clearance vehicle is recommended, along with off-road driving experience.

Bring spare tires, sunscreen, and ample water. Due to the lack of cell service, inform someone of your travel plans or bring a satellite communication device for emergencies.

Before heading out, make sure to review desert safety tips to better prepare for the unique challenges of this remote and beautiful landscape.
