Petrified Wood Polished Round Stump Escalante Utah
This small but really pretty polished round stump of Escalante, Utah Petrified Wood piece is 2.7 inches by 2.5 inches and .25 of an inch to .91 of an inch at its thickest.
This is a complete round with "bark" all the way around, slabbed and polished on one face and rough on the bottom.
Escalante Petrified Forest State Park is located north of Escalante in the Grand Staircase–Escalante National Monument in southern Utah.
This area is in the Morrison Formation, from the upper Jurassic period, 135 to 155 million years ago.
The petrified wood here is believed to be mostly conifers transported by a river before being buried and fossilized as agate.
The Grand Staircase–Escalante National Monument in Utah was established in 1996. Collecting is illegal in the area.
This piece was from an old collection and was self-collected in the 40's or 50's, prior to the establishment of the park.
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.
