Standout petrified wood spots in Oregon

Hand-picked from the full list below, with the reason each one earns a trip.

Hampton Butte
Deschutes County County
Hampton Butte, north of Brothers in central Oregon, is the classic source of green petrified wood, where Eocene wood was replaced by jasper and chalcedony and tinted by copper and iron minerals. Collecting on the surrounding BLM public land turns up petrified wood, limb casts, agate, and jasper, with the prized pieces ranging from turquoise to dark green. Mindat catalogs the locality in Deschutes County, and the wood has been documented in scientific studies of Oregon's fossil forests.
Warm Springs Reservoir
Harney County County
The high desert around Warm Springs Reservoir, on the Malheur River southeast of Burns, exposes weathered volcanic ground that yields agate, jasper, and petrified wood across public BLM land. Collectors find white, gray, and mossy agates alongside red and yellow jasper on the surface, with quality improving on the more remote ground away from the main roads. The reservoir lies in the broader Harney Basin rockhounding country that has drawn collectors to eastern Oregon for decades.
