Grassy Mountain Petrified Conifer Wood Polished Stone Rock
This Petrified Conifer Wood piece is slabbed and polished on one face, natural rough on the back and edges.
It is from Grassy Mountain in Southeastern Oregon, and it is 6.6 inches by 5.5 inches and .23 inch thick.
Grassy Mountain is a remote high desert rockhounding destination in Malheur County, near Owyhee Lake, Oregon and is well-known for the excellent quality of petrified wood.
The Grassy Mountain Formation of southeastern Oregon is from the Middle-Miocene age about 12.5 million years ago. For over a century, permineralized remains of stumps, logs, and branches have been recovered from several localities near Grassy Mountain.
The conifer wood, which typically has well-preserved cellular structures, appears in shades of beige, brown, orange, gray, and black.
This gemstone is the fossilized wood of trees. The Petrified Wood formed when a tree died and was buried by sediments. Minerals in the groundwater then permeated the wood, replacing the original organic matter and turning it to stone. The main mineral is silica, but trace elements in the silica create a variety of colors.
