Product Description
Gary Green Jasper Larsonite Petrified Bogwood Polished Rock
This is a pretty stand up piece of Larsonite that has been slabbed and polished on one face. It is also sliced on the bottom, but left rough everywhere else.
It is 4.7 inches tall by 4 inches at its widest and 2.35 inches thick.
It weighs 2.22 lbs. and does have some natural fracture lines.
This is petrified bog wood found near McDermitt, on the Nevada/Oregon border. It is called McDermitt Jasper, or Gary Green Jasper, or Larsonite.
During the Miocene Epoch, the trees we see preserved today as Larsonite were once living in a boggy habitat. A series of volcanic eruptions between 11 and 15 million years ago, with huge amounts of ash, knocked over the trees and buried them, depriving the plants of oxygen and halting the decaying process. Minerals from the volcanic ash then acted as the replacement material for this petrification/mineralization, giving the wood these vibrant colors.
