Where to Find Jasper in Oregon
Oregon jasper is concentrated on the Owyhee plateau and along the Deschutes drainage, with secondary fields scattered across the southeast desert. Morrisonite, from the Owyhee River canyon, is among the most prized picture jaspers in the world, with brown, blue, and cream landscape patterns set in a hard chalcedony matrix. The Biggs jasper field east of The Dalles produces tan-brown picture jasper with dendritic inclusions, while Bruneau jasper from the Idaho-Oregon border slips into the same color family. Closer to Madras, the Priday and Richardson Ranch beds yield green and red jaspers alongside their thundereggs.
