Cottonwood Creek, a high desert destination in Malheur County, Eastern Oregon, lies 32 miles southwest of Vale and 43 miles east of Juntura. The creek’s extensive gravel deposits offer opportunities to find jasper, picture jasper, agate, quartz, obsidian, and apache tears.

Shifting river channels and ancient lake deposits have shaped the area, leaving behind large gravel beds. Erosion and changing water levels continue to expose a diverse mix of rocks and minerals, making this a rewarding site for rockhounds.

To reach the area, follow Crowley Road, a dirt route south of Highway 20, leading to the creek. The first site, located at the bridge, is 9.5 miles from the highway.

A high-clearance 4WD vehicle is recommended, and travel is not advised during wet conditions. The area is remote, with limited services and cell coverage, so plan accordingly.

Cottonwood Creek Rockhounding

The best time to visit is during the dry season when the road is passable, and water levels drop, exposing large gravel deposits. Crowley Road meets Cottonwood Creek at the bridge, where searching can begin.

The next site is 2.7 miles away. Both locations yield picture jasper, jasper, agate, obsidian, and apache tears. Occasionally, pieces of quartz and petrified wood can be found.

Jasper is the most abundant find, appearing in red, brown, green, and yellow varieties. Picture jasper typically features light brown and green hues. Agate is scarce, with most pieces being clear. Large apache tears can also be found, with some reaching the size of a golf ball.

Surface collecting is the primary method here, though a geology pick can be useful.

Know Before You Go

Here are a few things you should keep in mind before heading to Cottonwood Creek:

4WD Vehicle: A high-clearance 4WD is highly recommended. The roads are rough and can be impassable after rain.
Remote Location: There are no services (gas stations, drinking water, or stores) within 20-30 miles of the site. Ensure your vehicle is fully fueled, and bring plenty of water and supplies. Cell service is spotty or non-existent.
Desert Wildlife: Watch out for rattlesnakes—they are common in this area.

Plan your trip. Bring enough water, sunscreen, and supplies to stay safe in the heat.

Familiarize yourself with desert safety practices to better prepare for the unique challenges of this remote and stunning landscape.
