Petrified Wood Polished Round Stump Escalante Utah
This really pretty polished on one face yellow and black Petrified Wood piece is from Henry Mountain, Utah and is 3.7 inches by 2 inches and about 7 inches long.
This is a complete round with "bark" all the way around, and it has been slabbed and polished on one slanted face.
The Henry Mountains are a group of peaks formed by volcanic activity and uplift.
It is part of the Morrison Formation, a sedimentary rock formation that dates to the Late Jurassic Period (approximately 155 to 150 million years ago).
Most of what is found in this rich deposit is Araucaria (conifer).
They are located in the Grand Staircase–Escalante National Monument in southern Utah.
The Grand Staircase–Escalante National Monument in Utah was established in 1996. Collecting is illegal in the area.
This piece was from the Kirkby 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.
