Petrified Wood Polished Rock Round Saddle Mountain Washington
This is a gorgeous colorful polished full round ('bark" all the way around) of Petrified Wood from Saddle Mountain, Washington.
The natural Petrified Wood slab is 8 inches and by 5.75 inches wide and slightly slanted from .6 to.7 inch thick.
Saddle Mountain Petrified Wood is found in the Columbia River Basalt Formation in Grant County, Washington.
Much of the petrified wood found at Saddle Mountain is distorted stumps. Complete rounds are rarer, particularly in larger sizes.
From the Miocene epoch of the Cenozoic era, about 15 million years old.
This petrifies wood is from an old collection, self-collected somewhere in the 40's to 70's.
Petrified Wood formed when a tree died and was quickly 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.
