Rocky Butte Picture Jasper is one of  the classic Oregon Picture Jasper varieties.  It is generally blue-gray and sepia, complete in many cases with dendrites to appear as “trees and bushes.”  The primary location of origin is the Owhyee Mountains of Eastern Oregon, near the Idaho border.  It is a porcelain jasper and only one of many varieties of Picture Jasper that comes out of this area.  This jasper is one of the more unusual of the picture jaspers and is widely known for its splendid array of colors and surreal scenery.
