Columbia River \/ Pacific Northwest river stones and glacial erratics commonly include granite and granodiorite (salt-and-pepper or multicolored speckled patterns of quartz, feldspar, and dark minerals like biotite\/hornblende). These are often collected as cobbles, tumbled or polished by collectors\/lapidarists, and sometimes modified with grooves (for wire-wrapping jewelry, drainage\/traction on larger pieces, or decorative effect). True local bedrock is dominated by Columbia River Basalt Group flows, but upstream\/tributary granite and metamorphic material mixes into the river system.\u003c\/p\u003e","brand":"Antique American Indian Art","offers":[{"title":"Default Title","offer_id":50548372635813,"sku":"221107-084","price":95.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/6071\/5685\/files\/221107-084_6.jpg?v=1790703064","url":"https:\/\/antiqueamericanindianart.com\/products\/columbia-river-polished-speckled-granite-stone-with-groove","provider":"Antique American Indian Art","version":"1.0","type":"link"}
