This is a lovely full round, slabbed, and polished on one side.
It is 4.95 inches by 3.9 inches and 8 mm or .3 inch thick.
Sunnyside, Washington had frequent occurrences of Taxodioxylon or cypress wood. This rare type of the species known as Taxodium ‘knees’ (which show the characteristic internal voids when sliced) came from an old collection and was originally collected on the Anderson Ranch in the Rattlesnake Hills of eastern Washington over 40 years ago!
The Sunnyside area is in Yakima Canyon, primarily north of Sunnyside and in the Rattlesnake Hills and on private property. The area has been closed to collecting for over 30 years.
In the middle of the Miocene epoch, about 17.5 million years ago, volcanic eruptions occurred near the borders of Washington, Oregon and Idaho. Forests were covered by lava and ash, resulting in numerous deposits of fossilized wood across the Columbia Plateau.
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.
