Richardson’s Rock Ranch

• Richardson’s Rock Ranch is known for its world-famous thunderegg deposits



Located northeast of Madras, a family owned Richardson’s Rock Ranch has been known for its extensive world-famous deposits of mineral-filled nodules or thundereggs. The highly-prized in the world Priday Plume agates features brilliant red and yellow plumes in the transparent matrix.

Besides local gems, the Richardson’s rock shop offers an exceptional selection of geological treasures from Oregon and all over the world.

This oasis for mineral collectors was open in 1974 and over decades remains one of the main attractions in Central Oregon.

The ranch has been extremely popular for digging opportunities. Currently, the owners closed beds to the public digging. However, visitors can purchase freshly dug thundereggs from the ranch beds including the famous Priday Agate Beds. In the shop, rockhound hobbyists will find rough and polished rocks, fossils, petrified wood, jewelry, and other products made from semi-precious stones.
