A family-run pay-to-dig thunderegg mine in the Ashwood country north of Prineville, working beds that have produced for decades. They put you on a face with a bucket and you keep what you pull. This is the low-friction way into the hobby around Bend: no claim research, no gate problems, someone shows you what a good egg looks like before you swing at it. PRIVATE, seasonal, call ahead.
Thundereggs, agate, jasper
