Exploring Twin Springs Rockhounding Area at the Owyhee Lake

Twin Springs is a premier rockhounding destination in Southeastern Oregon, located west of Owyhee Reservoir, approximately 20 miles southeast of Nyssa and 30 miles south of Vale.

This rugged, sagebrush-covered landscape is a haven for rock collectors, offering an impressive array of agate, jasper, petrified wood, chalcedony, calcite, and, on occasion, geodes. While minerals are abundant throughout the area, some locations yield higher concentrations than others.

Agates of various sizes can be found here, typically in shades of clear, white, blue, or gray. Many display distinctive features such as waterlines, mossy patterns, or intricate botryoidal and crystalline cavities.

Jasper is equally plentiful, with hues ranging from blue and green to gray and brown. These stones vary in size, from small, tumbled-ready pieces to larger, solid chunks ideal for cutting and polishing.

Surface collecting in the area can yield a variety of "float" materials scattered across sagebrush flats, old dumps, dry washes, and hillsides. Start by surface collecting to assess whether a spot appears promising.

We explored three different locations, with the last one proving especially rich in material. To navigate these areas, a rugged 4WD, high-clearance vehicle is highly recommended.

Be mindful of any claim markers to avoid trespassing, and always exercise caution when exploring these remote areas.
