Congleton Hollow beckons to rockhounds seeking petrified wood. Located 60 miles east of Prineville, this area is recognized by the Bureau of Land Management (BLM) as a designated recreational rock and mineral site and listed on the Central Oregon Rockhounding Map which is available for purchase.

Within the expansive 640 acres of this rockhounding haven, a splendid opportunity awaits enthusiasts to discover opalized petrified wood and limb casts with hues of blue, pink, and green. The ultimate prize is a larger tree trunk entirely replaced by agate, jasper, or quartz. Such specimens may boast quartz crystal cavities, dendritic inclusions, and captivating banding patterns.

Limb casts formed when molten lava envelopes and encased a tree that wasn't completely burned, creating a protective mold around the exterior surface of the limb. Over time, minerals from groundwater infiltrate the hollow cavity within the cast, leading to the deposition of various minerals like jaspers and chalcedony.

While Congleton Hollow has been a popular destination for decades, it continues to preserve areas where materials can be discovered right on the surface. Explore the hills and creek beds, which tend to be dry in the summer months.
