Biggs Picture Jasper Slab from Oregon

Oregon is famous for its wide varieties of picture jasper. So-called due to its resemblance to a layered landscape, Biggs Picture Jasper is found along the Columbia River near Biggs Junction, Oregon. An opaque variety of cryptocrystalline quartz (chalcedony), jasper is found worldwide. It owes its opacity and color to its incorporation of varying amounts of other minerals. Red to brown jasper is colored by hematite, yellow jasper by clay, and goethite can make it brown or yellow. There are many varieties of jasper including picture, brecciated, and leopard skin. Other deposits are found in the USA, Mexico, and Africa. Metaphysically, jasper imparts determination and courage.
